Parity Non Conservation Effects on Slow Neutrons Capture by Lead Nucleus

Abstract

More than thirty years ago high values of parity violation (PV) effects in comparison with theoretical evaluations in the scattering of slow neutrons experiments on Lead nucleus were observed. From scattering experiments resulted that the main contribution to the PV effects is given by the 204Pb isotope of Lead. Further in order to solve the discrepancy between theory and experiment on PV effects it was supposed the existence of a new so-called “negative” neutron P-resonance. In one of our previous work we have evaluated the PV effects on 204Pb isotope and using the existing experimental data the weak matrix element was extracted. With some uncertainty we demonstrated the possibility of the existence of a new P-resonance near the neutron threshold. Then we concluded that are necessary new data on PV effects in nuclear reactions induced by slow neutrons and one of the most convenient is the capture of the slow neutrons. In this work the asymmetry of emitted gamma quanta w
as evaluated in the frame of the formalism of the mixing states of the compound nucleus with the same spin and opposite parities. Combining the scattering and capture experimental and theoretical data it is possible first to extract the weak matrix element of PV process and the answer to the question of the existing of a new neutron P-resonance.
The present theoretical evaluations on PV effects in nuclear reactions by slow neutrons are dedicated to the preparation of new measurements at IREN (Intense Resonance Neutron), a neutron source of LNF – JINR.

Preface
This conference is the third in series of European Nuclear Physics Conferences, endorsed by the
European Physical Society. The first one was organized in Bochum in 2009 and the second one
in Bucharest in 2012. The following topics in nuclear and hadron physics and their applications
will be covered by this conference:
•Accelerators and Instrumentation
•Nuclear Structure, Spectroscopy, and Dynamics
•Nuclear Astrophysics
•Astroparticle Physics
•Heavy Ion Collisions and QCD Phases
•Hadron Structure, Spectroscopy, and Dynamics
•Fundamental Symmetries and Interactions
•Nuclear Physics Applications
•Few-Body Systems
The scientific part of the conference is composed of plenary talks (in the mornings), parallel
talks (in the afternoons) and one poster session on Thursday afternoon. The abstracts of
all the presentations are collected in this booklet according to their topical divisions. The
scientific program of this conference was composed by the international program committee
after consulting with the international advisory committee, both listed below.
This conference has used the generous support of several sponsors (listed below) to organize
a master class prior to the conference and to support many young physicists in the field and
those physicists coming from less-resourced countries.
We have made the program such that there is ample time for discussions outside the ses-
sions (during the coffee and lunch breaks) but also during the social events after the main
sessions. We wish you all a very fruitful conference and many new cooperative efforts.
On behalf of the local organizing committee and the international program committee,
Nasser Kalantar-Nayestanaki and Johan Messchendorp

Nuclear masses and their importance for nuclear structure, nuclear astro-
physics and fundamental studies
Klaus Blaum (Max Planck Institute for Nuclear Physics)
The mass of the nucleus reflects the total energy of this many-body system and thus is a key
property for a variety of nuclear structure and fundamental investigations. Modern experimental
techniques, like storage-ring or Penning-trap mass spectrometry, have pushed in recent years the
limits of sensitivity, resolution and accuracy. This has allowed to access exotic species very far
from the valley of beta-stability. The mass accuracy achieved even for very short-lived species in
the ms regime and below allowed, e.g., to probe the shell structures and their evolution toward
the neutron dripline or to perform in some regions fine examinations of the mass surface. This
includes many exciting results like, for instance, the establishment of a new, prominent shell closure
at neutron number N= 32, in excellent agreement with theoretical calculations. In addition,
with the nowadays achievable accuracy in Penning-trap mass spectrometry on short-lived exotic
nuclides, precision fundamental tests can be performed, among them a test of the Standard Model,
in particular with regard to the weak interaction and the unitarity of the Cabibbo-Kobayashi-Maskawa
quark mixing matrix. Furthermore, accurate mass values of specific nuclides are important for nuclear
astrophysics and neutrino physics as well as for the search of physics beyond the Standard Model. In
this review, recent trends in the determination of nuclear masses, their impact on nuclear structure,
nuclear astrophysics and fundamental studies and the comparison to modern calculations will be
presented.
Hard probes of the quark gluon plasma at the LHC
Marco van Leeuwen (Nikhef/Utrecht University)
Hard scattering processes in high-energy nuclear collisions produce energetic quarks and gluons that
probe the hot and dense matter that is created in the collisions as they escape the collision zone. I will
review recent experimental results concerning the production of high-pt particles and jets in heavy
ion collisions at LHC and what these results tell us about the the interactions between energetic
partons and the low-momentum quarks and gluons in the collision and the properties of the hot and
dense matter.
Tests of fundamental weak interactions and their symmetries using exotic
nuclei
Nathal Severijns (Kath. Univ. Leuven)
Precise measurements of observables in nuclear beta decay allow testing the symmetries of the
Standard Model or searching for physics beyond, at low energy. An update and overview of this field
will be presented based on selected state-of-the-art measurements in nuclear beta decay which use a
variety of techniques, many of which are based on ion and atom traps. With the precision of these
measurements reaching the per mil level small Standard Model effects now have to be included as
well. The understanding of some of these requires additional measurements be performed in order to
maintain optimal sensitivity to weak interaction properties. Finally, the prospects and future of this
type of low-energy weak interaction studies in the era of the Large Hadron Collider will be discussed
as well.

Hyperon physics - past, present and future
Karin Sch¨onning (Uppsala University, IKP-U)
Ever since first observed in experiment, hyperons have played an important role in our understanding
of fundamental interactions. In the early days of particle physics, the newly discovered Λ,Σand
Ξhyperons provided a key to the eight-fold way of the strong interaction from which the quark
model emerged. A basic question in hyperon physics is: What happens if we replace a light quark
in a nucleon with a heavier one?. The production of hyperons involves the creation of a heavy
(s,c,b) quark-antiquark pair, a process where the energy scale is governed by the mass of the
produced quark. The strange quark probes QCD in the intermediate domain between the non-
perturbative light-quark ChPT sector and the charm sector where perturbative QCD becomes more
relevant. Strange hyperons therefore provide a window to the strong interaction in a domain where
our understanding remains scarce. The weak, self-analysing decay of hyperons gives access to spin
observables. These are of interest for many reasons; for example as a test of CP violation in baryon
decays, the role of spin in strong interactions and hyperon electromagnetic structure. Hypernuclei
give unique possibilities to study nucleon-hyperon and hyperon-hyperon interactions, which in turn
give insight into e.g. neutron stars. This talk will focus on strange hyperons, what we have learned
from previous experiments and summarise ongoing activities at e.g. CERN, JLAB, JPARC, SLAC,
BEPC-II and DAPHNE. Finally, the unique opportunities provided at the future FAIR facility will be
outlined.
Electron spectroscopy of the heaviest elements
Rolf-Dietmar Herzberg (University of Liverpool)
A growing number of experiments is currently opening up the transfermium region of nuclei for
detailed spectroscopic investigations [1,2,3]. In the deformed nuclei in the nobelium region this
allows an identification and mapping of single particle orbitals closest to the top end of the nuclear
chart. Initial in-beam measurements in the region focussed on γ-ray spectroscopy of even-even
nuclei, studying the ground-state yrast bands and allowing extraction of parameters such as the
moments of inertia, and proving the deformed nature of these nuclei. More recently, it has become
possible to do combined in-beam gamma ray and conversion electron spectroscopy with the SAGE
spectrometer [4]. The first experiments have focused on the study of odd-mass transfermium nuclei
and are currently being analysed. These experiments will yield data which can be used to determine
the excitation energies and configurations of quasiparticle states in the region, and to compare them
to the predictions of various theories. Experimentally it is important to have a full understanding
of the instrument and GEANT4 simulations play an increasingly important role in the analysis of
experimental data [5,6].

Antihydrogen formation and trapping
Niels Madsen (Swansea University)
Antihydrogen, the bound state of an antiproton and a positron, can now be routinely formed and
trapped in in magnetic minimum traps. The first physics results with this intriguing system have
been carried out and many more are on the horizon. Antihydrogen is thus on the verge of delivering
on its promise of becoming an important test bed for fundamental physics and tests of fundamental
symmetries. In this presentation, we will give an overview of the developments that have led to these
remarkable results, review some of the key techniques involved and discuss ongoing and planned
measurements with antihydrogen.

A review of hadron spectroscopy from Lattice QCD: new ideas and results
Sinead Ryan (Trinity College)
Hadron spectroscopy from lattice QCD has entered a new era of precision. The spectrum of excited
and exotic single hadron states is determined for light and heavy mesons and baryons and the physics
of resonances is now being addressed. I will present recent results for spectroscopy, including exotic
and isoscalar states. New calculations of scattering states, including a coupled-channel analysis will
be discussed. The open questions and challenges for lattice hadron spectroscopy will be reviewed.
Quests in nuclear astrophysics
Zsolt F¨ul¨op (Atomki)
Nuclear physics is essential to understand the life cycle, energy release and nucleosynthesis processes
in stars. There are reactions in different burning phases, which are involved in the energy production,
evolution and nucleosynthesis of stars where our knowledge is limited: the cross sections of these
key reactions at astrophysically relevant energies are not known with the precision needed. Improved
data are required from nuclear physics to solve these problems and provide the next milestones for
the understanding of our present picture of the universe. In order to achieve those aims several
networks have been created recently to combine the astrophysical and nuclear fields. Among others,
two examples will be presented, the LUNA underground facility, where the inherent low background
allows to determine low cross sections for various astrophysical scenarios. Another example to be
presented is the current status of the astrophysical p-process, relevant for the production of certain
proton rich isotopes in explosive scenarios.
Radionuclides for medical applications
Ulli K¨oster (Institut Laue-Langevin)
Ionizing radiation plays an important role in many medical applications. Not only the specialties
radiology, radiotherapy and nuclear medicine rely on ionizing radiation, but also radioguided surgery,
certain dermatology procedures, research and development of new pharmaceuticals, etc. Last but
not least about half of all medical devices are sterilized by ionizing radiation before use. All these
applications use different types of radiation (gamma, positron, beta-minus, alpha, conversion and
Auger electrons), very different levels of dose, dose rate and activity respectively and different modes
of exposure (external versus internal). The dominating radionuclides in diagnostic nuclear medicine
are 99mTc for SPECT (single photon emission computed tomography) and 18F for PET (positron
emission tomography). These work horses are complemented by other diagnostic radionuclides with
shorter or longer half-lives or different chemical properties to cover a wide range of applications.
Therapeutic applications of radiopharmaceuticals were so far restricted to very special diseases (e.g.
thyroid cancer) but new targeted radionuclide therapies for more applications are now coming into
clinical practice. The future holds large promise for Theranostics, a type of personalized medicine
where a targeted radionuclide therapy is individually optimized based on imaging with a companion
diagnostic radiopharmaceutical. Such applications are ideally performed with so-called matched
pairs of diagnostic and therapeutic radionuclides of the same chemical element. The presentation
will discuss medical applications of radionuclides and the respective production methods. A particular
emphasis is made on synergies with nuclear physics research and research facilities.

Advances in nuclear structure with modern gamma spectrometers
Silvia Leoni (University of Milano and INFN Milano)
This talk will present selected highlights from recent campaigns in European Laboratories with mod-
ern Ge arrays. Particular attention will be dedicated to results obtained with the Advanced GAmma
Tracking Array (AGATA), during the campaign at Legnaro National Laboratory of INFN (Italy) and
GSI, employing different types of reactions, including fusion, inelastic scattering and multinucleon
transfer with heavy ions. Results from cold neutron capture and neutron induced fission measure-
ments performed at ILL (Grenoble) with the EXILL Ge array will be also discussed. It will be shown
how advanced gamma-spectroscopy studies can contribute to a deeper understanding of the structure
of the atomic nucleus in key region of the nuclear chart, around doubly magic nuclei or in exotic
systems. A detailed analysis of important nuclear structure phenomena, such as pygmy resonances,
coupling between single particles and phonon excitation and shape transitions will be discussed, to-
gether with the relevance of state of the art gamma spectroscopy for application in astrophysics and
applied physics.
Heavy flavor production and suppression in ultra-relativistic heavy ion colli-
sions
Silvia Masciocchi (GSI Helmholtzzentrum f¨ur Schwerionenforschung GmbH)
High-energy collisions of heavy nuclei produce a high-density, color-deconfined state of strongly
interacting matter called Quark-Gluon Plasma (QGP). Heavy-flavor hadrons, containing charm and
beauty, are important probes to study the characteristics and the evolution of the QGP. Heavy
quarks, in fact, are produced dominantly through hard partonic scattering processes in the earliest
stage of the hadronic collisions and thus they experience the whole history of the medium. RHIC
at the Brookhaven National Laboratory and the LHC at CERN have provided large statistics and
high quality data from nucleus-nucleus collisions, which allow precise investigations of the production
of heavy quarks and their interaction with the QGP. The variety and the precision of the available
measurements of the nuclear modification factor, the elliptic flow and correlations with hadrons,
suggest first constraints to theoretical models. An overview of the existing results and of the current
understanding of the heavy-flavor physics in heavy-ion collisions will be given.
Meson spectroscopy – methods, measurements and machines
Klaus G¨otzen (GSI Helmholtzzentrum f¨ur Schwerionenforschung GmbH)
The discovery of a new zoo of hadronic resonances in the heavy and light meson sector in the past
decade created new momentum of interest in the field of hadron and in particular meson spectroscopy.
Many of the so-called XYZ states are not well understood, the same holds for some of the newly found
open charm resonances. The large number of new states on the one hand offers the opportunity to
gain a deeper understanding of the properties of QCD bound states, on the other hand requires the
development of new ordering schemes and the completion of multiplets in order to identify the proper
theoretical description. Apart from a selection of recent puzzling observations, analysis techniques
and different types of experiments will be discussed.
Recent highlights on in-beam gamma spectroscopy of rare isotopes
Alexandre Obertelli (CEA Saclay)
The past few years, a new level of sensitivity for the structure of neutron-rich nuclei via in-beam
gamma spectroscopy has been reached. New generation high resolution photon arrays have become
available and used at Radioactive Isotope facilities. The Radioactive Isotope Beam Factory of RIKEN,
today’s leading machine to produce radioactive ions at intermediate energies, succeeds in producing
Uranium, Zinc and Calcium primary beams at very high intensities (above 15, 50 and 200 pnA,
respectively). Additional developments, such as the MINOS hydrogen target, contribute in reaching
unknown regions of the nuclear landscape. The most recent achievements in nuclear structure of
rare isotopes obtained from in-beam gamma spectroscopy worldwide will be presented.

Invited Plenary Contributions 33
Perspectives in superheavy element research
Julia Even (TRIUMF)
Superheavy elements provide unique opportunities to study nuclear structure and the influence of
relativistic effects on the electron shell. So far, the elements up to proton number 118 have been
discovered and their nuclear decay properties have been investigated. Recently, improved and new
experimental techniques provided excess to the atomic, nuclear and chemical properties of the heav-
iest elements. I will give an overview on the latest research highlights and a personal view on the
future of the research field of the heaviest elements.
Fluctuations and flow of the world’s smallest and hottest fluid
Bjoern Schenke (Brookhaven National Laboratory)
Experiments at particle colliders including the Relativistic Heavy Ion Collider at Brookhaven National
Laboratory and the Large Hadron Collider at CERN have found that the matter created in heavy ion
collisions behaves like an almost perfect fluid. This conclusion relies on the success of hydrodynamic
models in describing the bulk features of the collision when a well motivated fluctuating initial state
is used. I will review progress in describing this initial state as a dense system of gluon fields using an
effective theory of QCD in the high energy limit. I will then discuss its implementation into relativistic
viscous fluid dynamic calculations and compare results of the calculation to experimental data from
RHIC and LHC. These comparisons can be used to constrain the values of the shear and bulk viscosity
of the created system. Furthermore, I will address recent measurements of particle correlations in
very small collision systems involving at least one proton projectile that show very similar behavior
to heavy-ion collisions. I will discuss whether one can interpret these results as signals of similar
collective behavior as we see in heavy ion collisions or whether alternative mechanisms are important
in these very small systems.
Light Dark Matter search at accelerators
Marco Battaglieri (INFN Genoa)
In the last few years interest for Light Dark Matter (LDM) in the MeV - GeV range has been
increasingly growing. Direct detection of non-relativistic dark matter particles in the Galactic halo
mainly focused to higher masses(>10 GeV) being insensitive to few-GeV or lighter DM, whose nuclear
scattering transfers invisibly small kinetic energy to a recoiling nucleus. On the other hand availability
of high intensity, high precision and moderate energy electron beams allow for testing different LDM
scenarios leaving to accelerator-based experiments the opportunity to explore an equally promising
but uncovered territory. In this talk I will review the latest experimental results for LDM searches as
well as the new experiments proposed in different laboratories.
Probing QCD phase boundary in Heavy Ion Collisions
Krzysztof Redlich (University of Wroclaw)
We introduce the structure of the QCD phase diagram related with deconfinement and chiral sym-
metry restoration. The theoretical results will be based on the first principal lattice QCD and model
calculations. We discuss the phenomenological probes of the QCD phase boundary in Heavy Ion col-
lisions. In this context we focus on measured properties of correlations and fluctuations of conserved
charges to identify the phase change due to the chiral symmetry restoration. We consider charmonia
production yields as a probe of deconfinement in a medium created in high energy nuclear collisions
at RHIC and LHC.

Quasi-free scattering from radioactive nuclei
Lola Cortina (Universidad de Santiago de Compostela)
Quasi Free Scattering can be understood as a process in which a high energy particle knocks a nucleon
out of a nucleus without any further significant interaction between the nucleon and the incident
and the outgoing particles. This reaction mechanism allows to probe both valence and deeply-
bound nucleon including those leading to unbound states. QFS experiments are thus considered a
quantitative tool for studying single-particle occupancies and correlation effects in the nuclei. They
have been mostly exploited through direct kinematics reactions of proton beams at high energy on
stable nuclear targets. The recent use of this reaction channel in inverse kinematics, opens the exciting
possibility of exploring nuclear structure for unstable nuclear species. This kind of investigation is one
of the physics case to be addressed with the R3B (Reactions with Relativistic Radioactive Beams)
collaboration. The study of 12C(p, 2p)reaction at 400 A.MeV was successfully undertaken at the
present ALADIN-LAND GSI setup (predecessor of R3B) to show the feasibility of inverse kinematics
QFS studies. The results obtained with this stable nucleus will be presented in this paper. These
data will be completed with preliminary measurements preformed on other light exotic isotopes. The
upgrade of the actual experimental setup to the final R3B/FAIR will also be presented.
Nuclear matrix elements for fundamental symmetries
Javier Menendez (University of Tokyo)
Atomic nuclei are ideal laboratories to test the fundamental symmetries of Nature in low-energy
experiments. Neutrinoless double-beta decay is a lepton-violating process which will only occur
if neutrinos are Majorana particles. Decay lifetimes depend on the masses of the neutrinos and
on the nuclear matrix elements of the transition. Therefore, nuclear matrix elements are crucial
to guide experimental searches and, once detection has been achieved, to extract information on
neutrino masses. In this talk I will discuss the theoretical calculation of neutrinoless double-beta
decay matrix elements, emphasizing the impact of nuclear structure effects such as pairing and
deformation correlations. The nature of dark matter is one the major challenges in physics today.
Direct detection experiments aim to measure the scattering of dark matter particles off nuclei. The
matrix elements of the scattering process are key for experimental analyses, and to elucidate the
interaction between the dark matter particles and the nucleons. I will present state-of-the-art matrix
element calculations of the scattering of WIMPs (weakly interacting massive particles) off xenon,
which presently set the most stringent limits for direct detection of dark matter.
A new era for jet studies in ultra-relativistic heavy-ion collisions
Jose Guilherme Milhano (CENTRA-IST (Lisbon) and CERN)
I will review recent theoretical and phenomenological developments on the use of jets as powerful and
detailed probes of the Quark-gluon plasma produced in ultra-relativistic heavy-ion collisions at the
LHC and RHIC. As a conclusion I will provide an assessment of the future of this research programme.
Seeing the high energy universe (with neutrinos)
Subir Sarkar (University of Oxford and NBI Copenhagen)
The detection of high energy neutrinos of extraterrestrial origin by the IceCube detector buried in
the Antarctic icecap has opened a new window in astronomy. Efforts are underway in the KM3NeT
project to construct a similar detector in the Mediterranean sea, so we will have a view of the full
sky. We can then identify whether e.g. active galactic nuclei or gamma-ray bursts or something
even more exotic are the sources of the highest energy particles in the universe. These experiments
also measure to high precision the oscillations of neutrinos produced by cosmic ray interactions in
the atmosphere, and can detect subtle matter effects as they pass through the Earth. Searches are
also being carried out for neutrinos from the annihilation of dark matter accreted by the Sun or
clustered in the Galactic halo, for neutrino pulses from core-collapse supernovae, etc.. I will describe
this exciting physics programme.

Light baryon spectroscopy - recent results from photoproduction experiments
Ulrike Thoma (HISKP, Uni Bonn)
One of the open challenges in subnuclear physics is to understand the non-perturbative regime of
quantumchromodynamics, including the world of the nucleon and its excitations. One of the key
issues here is to identify the relevant degrees-of-freedom and the effective forces between them. A
necessary step towards this aim is undoubtedly a precise knowledge of the experimental spectrum and
the properties of baryon resonances. Recently, photoproduction experiments have made large progress
providing not only differential cross section measurements but also high quality single and double
polarization observables. Without the measurement of such polarization observables an unambiguous
partial wave analysis to finally extract the contributing resonances from the data is not possible. In
the talk, among other results, results from the recent double polarization experiments at ELSA, JLab
and MAMI will be discussed.
Evolution of low-energy nuclear collective excitations
Dario Vretenar (Physics Department, Faculty of Science, University of Zagreb)
Low-energy collective excitations reflect the underlying effective nuclear interactions and shell struc-
ture of single-nucleon orbitals. The evolution of collective states characterizes a variety of interesting
structure phenomena across the nuclide chart: clustering in light nuclei, modification of shell struc-
tures and occurrence of deformations in closed-shell nuclei far from stability, location of the drip-line
in neutron-rich nuclei, shape coexistence and shape transitions in medium-heavy and heavy nuclei,
low-energy resonances and the formation of neutron skin, octupole correlations, subshell closures in
deformed superheavy nuclei, etc. An accurate modeling of low-energy collective excitations presents
a challenge and crucial test for any theoretical approach. The microscopic self-consistent mean-field
method that uses effective interactions or universal energy density functionals, provides a complete
and detailed description of ground-state properties and collective excitations, from relatively light
systems to superheavy nuclei, and from the valley of beta-stability to the particle drip-lines. Based
on this framework, structure models have been developed that go beyond the static mean-field
approximation and include collective correlations related to restoration of broken symmetries and
fluctuations of collective variables. These models have become standard tools for nuclear structure
calculations, able to describe and explain a wealth of new data from radioactive-beam facilities, the
exciting phenomenology of nuclear astrophysics, and provide microscopic predictions for low-energy
nuclear phenomena.
Experimental studies of Generalized Parton Distributions
Silvia Niccolai (JLAB)
Generalized Parton Distributions (GPDs) are nowadays the object of an intense effort of research,
in the perspective of understanding nucleon structure. They describe the correlations between the
longitudinal momentum and the transverse spatial position of the partons inside the nucleon and they
can give access to the contribution of the orbital momentum of the quarks to the nucleon spin. Deeply
Virtual Compton scattering (DVCS), the electroproduction on the nucleon, at the quark level, of a
real photon, is the process more directly interpretable in terms of GPDs of the nucleon. Depending
on the target nucleon (proton or neutron) and on the DVCS observable extracted (cross sections,
target- or beam-spin asymmetries,...), different sensitivity to the various GPDs for each quark flavor
can be exploited. This talk will be focused on recent promising results, obtained at Jefferson Lab,
on cross sections and asymmetries for DVCS, and their link to the Generalized Parton Distributions.
These data have opened the way to a “tomographic” representation of the structure of the nucleon,
allowing the extraction of transverse-space densities of the quarks at fixed longitudinal momentum.
The extensive experimental program to measure GPDs at Jefferson Lab with the 12-GeV-upgraded
electron accelerator and the complementary detectors that will be housed in three experimental Halls
(A, B, C), will also be presented.

Interpretation of new states in open/hidden quarkonium
Fulvia De Fazio (Istituto Nazionale di Fisica Nucleare, Sezione di Bari)
I discuss recent experimental results in heavy meson spectroscopy, both in open and hidden flavour
cases. In the case of open charm and beauty mesons, adopting an effective Lagrangian approach
based on the heavy quark and chiral symmetry, individual decay rates and ratios of branching fractions
can be computed. I discuss how the results allow to assign the quantum numbers to recently
observed charmed states which still need to be properly classified and to derive predictions for the
corresponding beauty states. Finally, I consider the possibility of extending this approach to hidden
flavour quarkonia.
Status and perspectives of the ELI-NP facility
Calin Alexandru Ur (ELI-NP)
Extreme Light Infrastructure Nuclear Physics (ELI-NP) is a research facility aiming to use ex-
treme electromagnetic fields for nuclear physics research. The facility will comprise two major re-
search instruments: a high power laser system and a very brilliant gamma beam system. The high
power laser system will consist of two 10 PW APPOLONtype lasers providing intensities of up to
1023 −1024 W/cm2. The gamma beam, produced via Compton backscattering of a laser beam on a
relativistic electron beam, will be characterized by high spectral density of about 104photons/s/eV,
a narrow bandwidth (less than 0.5%) and tunable energy of up to 20 MeV. The scientific interest
of ELI-NP is covering a broad range of key topics in frontier fundamental physics and new nuclear
physics. The experimental activity of the facility is focused on three directions: highpower laser
studies, experiments with gamma beams and combined measurements with highpower lasers and
gamma beams. Some of the main research topics of interest are: laser driven nuclear physics exper-
iments, characterization of the lasertarget interaction by the means of nuclear physics instruments,
photonuclear reactions, exotic nuclear physics and astrophysics. A particular attention is also given to
the development of innovative applications based on the use of both high power lasers and brilliant,
narrow bandwidth gamma beams. The status of the project and the main research topics proposed
to be studied at ELI-NP will be discussed.
Pear-shaped nuclei measured via Coulomb excitation at REX-ISOLDE
Liam Paul Gaffney (KU Leuven - Instituut voor Kern- en Stralingsfysica)
Pear-shaped nuclei, those having quadrupole-octupole deformation, are predicted to occur in around
the octupole magic numbers of 34, 56, 88 and 134. At these numbers of neutrons and protons,
the Fermi surface lies close to single-particle orbitals with quantum numbers [l, j ]and [l−3, j −3].
This enhances particle-hole interactions in the octupole part of the nucleon-nucleon force and is
the driver of octupole collectivity. In the heaviest nuclei (Z∼88 and N∼134), this interaction is
expected to be the strongest leading to the largest octupole deformations. Here, 220 Rn and 224Ra
were studied in ground-breaking Coulomb excitation experiments at the Radioactive Ion Beam facility,
REX-ISOLDE [1]. These experiments provided only the second measurements of E3 matrix elements
in the radium isotopes (following 226Ra) and the first such measurement in radon. The results that
will be presented in this talk are interpreted in terms of deformation and compared to state-of-the-art
mean field calculations. The results are not only significant for nuclear structure, but also on the
search for atomic EDMs. The consequence of our results for experiments designed to use octupole-
deformed nuclei as a laboratory in their search for EDMs, will also be discussed. Additionally, the
next steps in the project showing the first Coulomb-excitation experiments of an odd-mass nucleus
in this region and plans for more sensitive measurements at HIE-ISOLDE, will be presented.

Relativistic Chiral EFT with baryons: recent developments and future pros-
pects
Jose Manuel Alarcon (Helmholtz-Institut f¨ur Strahlen- und Kernphysik, Universit¨at Bonn)
In this talk I will present some of the recent developments in relativistic Chiral Effective Field Theory
with Baryons. I will focus on the application of this formulation to the pion-nucleon scattering process
at low energies, and on how to extract important information out of this reaction with Chiral EFT. As
the most prominent example, I will consider the extraction of the pion-nucleon sigma term, which has
been object of debate during many years. I will show that modern experimental information points
to a value of the sigma term close to 60 MeV. I will also discuss the phenomenological implications
of this relatively large value, making special emphasis on the strangeness content of the nucleon.
Finally, I will show how the so-known Strangeness Puzzle is solved by the relativistic formulation of
Chiral EFT, giving rise a picture of the sigma-term and strangeness content of the nucleon consistent
with experimental information and lattice QCD calculations. The outreach of these results in current
and future applications will be discussed as well.

CERN ISOLDE facility in the framework of a systematic ultra-fast timing [1] investigation of neutron
rich nuclei populated in the decay of Zn. The use of the ISOLDE RILIS and a cooled transfer line
between the ion source and the target [2] made it possible to produce a pure beam of 81Zn ions,
which was delivered to our compact fast-timing station equipped with two LaBr3(Ce) detectors, a
plastic scintillator and two HPGe detectors. In this work, we present the 81Ge results arising from
the analysis of the γ-γHPGe coincidences and the fast-timing analysis based on β−γ(t) and
β−γ−γ(t) events involving the fast scintillators. The level scheme presents 10 new levels and 15
new γtransitions with respect to the recent studies [3]. The decay half-life of 81Ga was determined
by using the strongest γ-rays from the decay. Several half-lives of excited states up to 2 MeV in 81Ge
have been measured. Based on these measurements and the improved level scheme, the spin-parity
assignments will be discussed and compared with shell-model calculations.

An enhanced collectivity was discovered in the N= 40 Cr and Fe isotopes, but its evolution beyond
N= 40 and the maximum of collectivity remains unknown. The first campaign of the Shell Evolution
And Search for Two plus Energies At the RIBF (SEASTAR) scientific program took place in Spring
2014 at the Radioactive Isotope Beam Factory. It focused on the first spectroscopy of the more
neutron-rich attainable nuclei such as Cr and Fe N > 40 isotopes via proton-knockout reactions with
the unique coupling of the DALI2 gamma array with the MINOS device. MINOS is composed of a
thick liquid hydrogen target and a Time Projection Chamber (TPC). The charged particles produced
by knockout reactions are detected in the TPC and enable the reconstruction of the reaction vertex
with the use of a tracking algorithm, thus ensuring an optimal Doppler correction for the measured
γ-rays by DALI2. The first analysis results of the SEASTAR campaign will be presented with the
first spectroscopy of 66Cr and 70,72 Fe. The performances of the MINOS TPC will also be detailed.

Mass and isospin dependence of short range correlations in nuclei
Camille Colle (Ghent University), Jan Ryckebusch, Wim Cosyn, Or Hen, Eliezer Piasetzky,
Igor Korover, Lawrence Weinstein
The nuclear momentum distribution (NMD) is often quoted as being composed of two separate
parts. Below the Fermi momentum (250 MeV/c) single nucleons move as independent particles in a
mean field created by their mutual interactions. Above the Fermi momentum nucleons predominantly
belong to short-range correlated (SRC) pairs with high relative and low center-of-mass momenta,
where high and low are relative to the Fermi momentum. In addition to its intrinsic interest, the
NMD is relevant to two-component Fermi systems, neutrino physics, and the symmetry energy of
nuclear matter. The nuclear mass dependence of the number of SRC proton-proton (pp) and proton-
neutron (pn) pairs in nuclei is a sensitive probe of the dynamics of short-range pairs in atomic nuclei.
The amount of the number of SRC pairs in a nucleus can be investigated with electroinduced two
nucleon knockout reactions (A(e,e’NN) in brief). Thereby, a nucleon and its correlated partner are
knocked out. We present an analysis of (e, e0pp)and (e, e0p)data on 12C, 27Al, 56 Fe, and 208Pb in
kinematics dominated by scattering off SRC pairs and compare the results with theoretical models.
The nuclear mass dependence of the extracted number of pp- and pn-SRC pairs is very soft. Final
state interactions of the outgoing nucleons with the A-2 nucleus play a significant role. The two
dominant contributions are (1) attenuation trough elastic and soft inelastic rescattering and (2)
charge exchange reactions, changing the isospin projections of the outgoing nucleons.

Among the weak processes in nuclei, Gamow-Teller (GT) transitions caused by the -type interaction
are very popular. They play important roles, for example, in the early stage of the core collapse of su-
pernovae. Studies of GT strenghts B(GT )in pf-shell nuclei using (p, n)and (n, p)Charge-Exchange
(CE) reactions at intermadiate energies started in the 1980s. They provided rich information on
the overall GT strenght disributions but individual transitions were only poorly studied due to their
limited energy resolutions of 300 keV. A development in precise beam matching techniques realized
an energy resolution of 30 keV in intermediate energy (3He, t)reactions at 0◦. With this one order
of magnitude better resolution, GT and Fermi states that were unresolved in the pioneering (p, n)
reactions can be studied. In order to study the Gamow-Teller (GT) transitions from the Tz=+3
nucleus 50Ti to the Tz= 2 nucleus 50V, where Tzis the zcomponent of isospin T, we performed a
(p, n)-type (3He, t)charge-exchange (CE) reaction at 140 MeV / nucleon and the scattering angles
around 0◦. An energy resolutions of 21.5 keV, that was realized by applying matching techniques
to the magnetic spectrometer system, allowed the study of fragmented states. Assuming the pro-
portionality between reaction cross-sections and GT transition strengths B(GT ), the B(GT )values
were derived up to the excitation energy (Ex) of 15 MeV.

Gamow-Teller is a weak interaction of spin-isospin type. By studying GT transitions we can obtain
some information about nuclear structure as well as nuclear astrophysics. GT transitions can be
studied by beta decay and charge exchange reactions. beta-decay has a direct access to the absolute
GT transition strengths B(GT ). Charge Exchange reactions are also useful to determine B(GT )
strengths up to high excitation energies if the standart B(GT )value is available from beta-decay
studies. Here in this talk we focus on high-resolution (3He, t) type charge exchange reaction studies
at RCNP, Osaka. A specific example on the 46 Ti target nucleus will be given. The spectrum which
have high energy resolution of 30.25 keV makes it possible to observe many excited states and
determine the Gamow-Teller transition strengths in 46 V.
Recent results from the mass spectrometer ISOLTRAP
Andree Welker (CERN)
Atomic masses of radioactive nuclides provide crucial information for a number of research topics,
from nuclear structure and its manifestations across the nuclear chart, to the modelling of the
rprocess of nucleosynthesis. In this contribution, we will present the latest mass measurements
from the precision Penning-trap mass spectrometer ISOLTRAP, located at the ISOLDE facility at
CERN. The masses of neutron-rich 129−131Cd isotopes were determined using ISOLTRAPs unique
combination of four ion traps, including a multi-reflection time-of-flight mass spectrometer, which
is now used for beam purification and mass spectrometry as well. The cadmium isotopes are an
important input for modelling the astrophysical rprocess of nucleosynthesis, as the 130Cd isotope is
thought to be a major waiting point nuclide. The masses of neutron-rich chromium isotopes were
measured, approaching the N = 40 region, where nuclear collectivity is expected. Additionally, the
masses of 101,102Sr and 101,102 Rb were determined, extending the investigations of the A ≈100
nuclides in a well-known region of nuclear shape transition.
Shell model calculation on even-even Germanium isotopes
Amin Attarzadeh (Department of Physics, PNUM university, Mashhad), Saeed Mohammadi
Energy levels and the B(E2) values of even- even 70−76Ge isotopes have been calculated through
shell model calculations using the shell model code OXBASH for windows, employing the SLG model
space and SLGM interaction. The energy level calculations were in good agreement with experimental
data. The B(E2) values and β2, the quadrupole deformation parameter, results were consistent with
the available experimental data.

Probing nuclear properties of imbalanced fermi systems with quasi-free proton
knock-out reactions
Sam Stevens (Department of Physics and Astronomy, Ghent University, Belgium), Jan Rycke-
busch, Wim Cosyn
Quasi-free knockout reactions in inverse kinematics offer great opportunities to probe the mean-field
properties of imbalanced nuclei. We have developed a reaction model for quasi-free A(p, pN )B
reactions with unstable nuclei. Such a model makes it possible to connect experimental data from
(p, pN )measurements in inverse kinematics at radioactive-beam facilities, to the mean-field proper-
ties (spectroscopic factors and single-particle wave functions). The cross sections are calculated in a
factorised way. To incorporate the effect of the soft initial- and final-state interactions, a Relativistic
Multiple Scattering Glauber Approximation (RMSGA) is used. Soft interactions are calculated in an
eikonal approximation using the free scattering cross sections. The role of charge-exchange effects is
computed in a semi-classical way. The single-particle wave functions for the momentum distributions
are from a mean-field shell-model calculation. The results of the model are compared to the mo-
mentum distributions for (p, 2p)reactions on 9-16C isotopes at 250 MeV/A, obtained at the HIMAC
accelerator in Chiba, Japan. By comparing the theoretical cross sections to these distributions, we
can study the evolution of the shell-model parameters as a function of Z/N. The model that is de-
veloped can serve to analyse the resulting data from experiments with relativistic radioactive beams
conducted at GSI.
Evaluation of some nuclear physics constants by isomer ratios of Tin
Cristiana Oprea (JINR), Alexandru Mihul, Alexandru Oprea
In the present work the photoneutron reactions of Sn and (p, n)reaction on Indium for Tin isotopes
production will be analyzed. For both processes the cross sections for energy of incident particles of
order of MeVs were estimated. The contributions of different nuclear reaction mechanisms and the
corresponding influence of nuclear potentials in the cross sections were obtained. The cross sections
calculations were used in the isomer ratios evaluations of Tin isotopes. Later in the modeling of Tin
isotopes production in (p, n)and photoneutron reactions were employed. The theoretical results were
compared with the experimental data. From cross sections and isomer ratios data were extracted
some important data for nuclear structure like binding energy of neutron and energy values for gamma
transitions.
Isovector proton-neutron pairing and Wigner energy in Hartree-Fock mean
field calculations
Daniel Negrea (National Institute of Physics and Nuclear Engineering, Bucharest, Romania),
Neculai Sandulescu
We propose a new approach for the treatment of isovector pairing in self-consistent mean field
calculations which conserves exactly the isospin and the particle number in the pairing channel.
The mean field is generated by a Skyrme-HF functional while the isovector pairing correlations are
described in terms of quartets formed by two neutrons and two protons coupled to the total isospin
T= 0. In this framework we analyse the contribution of isovector pairing to the symmetry and
Wigner energies [1]. It is shown that the isovector pairing is able to provide a good description of the
Wigner energy, which is not the case for the mean field calculations in which the isovector pairing is
treated by BCS-like models.

Clustering features of light neutron-deficient nuclei in nuclear fragmentation
Denis Artemenkov (JINR)
Nuclear track emulsion (NTE) is still retaining its exceptional position as a means for studying the
structure of diffractive dissociation of relativistic nuclei owing to the completeness of observation of
fragment ensembles and owing to its record spatial resolution. Separation of products of fragmen-
tation and charge-exchange reactions of accelerated stable nuclei make it possible to create beams
of radioactive nuclei. At the JINR Nuclotron exposures of NTE stacks of (NTE) are performed at
energy above 1 A GeV to the beams of isotopes Be, B, C and N, including radioactive ones [1-3].
In general, the results confirm the hypothesis that the known features of light nuclei define the
pattern of their relativistic dissociation. The probability distributions of the final configuration of
fragments allow their contributions to the structure of the investigated nuclei to be evaluated. These
distributions have an individual character for each of the presented nuclei appearing as their original
autograph. The nuclei themselves are presented as various superpositions of light nuclei-cores, the
lightest nuclei-clusters and nucleons. Recent data on pattern of diffractive dissociation of the nuclei
9C, 10C, 11 C and 12N will be discussed in this context.

Pairing in 6He, Giant Pairing Vibrations in Carbon and pair-transfer in reac-
tions
Lorenzo Fortunato (Dept. of Physics and Astronomy - Univeristy of Padova)
Pairing phenomena emerge in nuclear structure and in reactions involving a transfer of correlated
pairs. We will give an account of the studies on this topic that have been carried on at our institute
in collaboration with several other groups. The low-lying bound ground state and continuum states
of 6He are constructed starting from neutron single-particle unbound p-resonances of the 5He system
plus pairing interaction. We compare our findings with available databases (TUNL, NNDC) and with
more recent experimental works [1]. This model is realistic and can give detailed information on how
to disentangle the sometimes contrasting experimental results. We discuss also recent experiments
performed by the group in Catania LNS [2] that show strong signatures of the presence of the Giant
Pairing Vibration, a collective mode built out of particle-particle and hole-hole excitations, in transfer
reactions involving Carbon isotopes, where the energy spectrum is measured up to the region where
this resonance is expected. As a third example of the importance of pairing in nuclei, we discuss
several calculations for two-neutron transfer reactions on various targets of certain relevance for
present-day experiments, such as 32Mg and 68Ni [3]. These calculations show how to determine the
wavefunction ”content” in terms of ratio of cross-sections.

Ab initio study of radiative captures and nucleus-nucleus bremsstrahlung
J´er´emy Dohet-Eraly (TRIUMF), Petr Navr´atil, Sofia Quaglioni, Guillaume Hupin
The recent progresses in the development of ab initio approaches make possible the description of
bound and scattering states for light nuclear systems in a unified framework, based on microscopic
Hamiltonians built within chiral effective theory. Among these approaches, the No-Core Shell Model
with Continuum (NCSMC) [1] has proven particularly successful for studying resonances and elastic
scattering of five- and six-nucleon systems [2,3]. The extension of this approach to the description
of electromagnetic transitions in nuclear systems is highly desirable. It will be useful to probe the
quality of the ab initio wave functions and in particular, to evaluate radiative cross sections including
at energy ranges out of reach of experiments. I will present the first attempts to describe radiative
captures and nucleus-nucleus bremsstrahlung with the NCSMC. I will discuss the applications of this
method to the astrophysically important 3He(α, γ)7Be and 3H(α, γ)7Li reactions and to the αN
bremsstrahlung [4], a preliminary step towards the study of the t(d, γn)αbremsstrahlung, considered
as a possible plasma diagnostic in fusion experiments [5].

Lifetime measurements in Rb isotopes around the N= 50 shell closure
Cristina-Roxana Nita (Horia Hulubei National Institute for Physics and Nuclear Engineering
(IFIN-HH))
The half-lives of yrast states in 86,87Rb isotopes, produced in 82Se(7Li, xn)reactions, were measured
using the ROSPHERE gamma spectrometer. The experimental evidences prior to this measurements
lead to the conclusion that 1p−2H proton configurations which involve the g9/2,f5/2,p3/2orbitals
are energetically favored to appear in this mass region with N∼50 for states at excitation energies
lower than ∼4MeV. At higher excitation energies, the neutron core breaks and neutron p−h
excitations have to be considered. The proton hole f5/2p3/2orbitals are responsible for delayed
gamma decay of these states in neighboring Kr isotopes, having lifetimes in the nanosecond region.
It is expected that this configuration to determine the existence of an isomeric state in 87Rb. Also,
the experimental evidence concerning the spins and parities for these states located at a medium
excitation energy in 87Rb is rather scarce. Of interest in the present work was to investigate the
structure of excited states in the Rb isotopes, using the in-beam fast timing technique. From this
measurements, the gamma decay multipole could be deduced.

The isospin-forbidden proton emission of proton-rich sd- and pf- shell nuclei
Yek Wah Lam (Inst. of Modern Physics, Chinese Academy of Sciences), Nadezda A. Smirnova
The study of beta-delayed decay modes of nuclei near the proton drip line is pivotal for nuclear-
structure physics in understanding the role of isospin impurity in the states of outermost imbalance
of the proton and neutron numbers with respect to stable nuclei. The mechanism of a beta-delayed
decay involves first a beta decay, with the highest probability for a superallowed beta-decay to the
isobaric analogue state (IAS), followed by a proton or multi-particle emission. This second-stage
proton (or multi-particle) emission from the high-lying IAS is isospin-forbidden, while decay from
Gamow-Teller populated states may proceed according to the isospin-symmetry limit. A precisely
measured exotic decay scheme and branching ratios for an isospin-forbidden and/or allowed particle
emission provide a stringent and sensitive test for a microscopic approach that takes into account
isospin non-conservation (INC). With our recently constructed INC Hamiltonians, we calculated the
partial decay schemes of some precursors, e.g., 25Si, 29 S, 33Ar, 37 Ca, 53Ni, etc., within large-scale
shell model approach. The microscopic description with an INC Hamiltonian enables us to take
into account the isospin-symmetry breaking consistently in all physics processes under consideration,
namely, beta decay, proton emission and electromagnetic de-excitation. The results show an excellent
agreement with available experimental data.

Modeling nuclear reactions of light nuclei: transition between microscopy and
phenomenology
Thomas Srdinko (TU Wien, Atominstitut), Helmut Leeb
In general standard reaction theory combined with proper nuclear and Coulomb interactions lead to
fair description of nuclear reaction cross sections. The situation is less satisfying for reactions in
the resonance regime because there is no proper method available to determine the positions and
widths of resonances. Hence the resonance region is usually described via R-matrix theory which
provides an excellent description of cross sections if the positions and widths of the resonances are
known. At present the transition to the region with a continuous level density at higher energies is
intriguing. This is particularly disturbing for the nuclear data evaluation of light nuclei. In the present
contribution we propose a method which guarantees the continuous transition between resonance
regime and standard reaction calculations based on the statistical model as well as on coupled-channel
calculations. In order to find a proper method the R-matrix technique is well suited. On the one
hand it provides an excellent phenomenological description of the resonance region. On the other
hand it represents a method for the solution of coupled-channel equations. Combining both aspects
of the R-matrix theory offers a promising route towards the goal of a continuous transition. Work

Interplay of γ-rigid and γ-stable collective motion in the phase transition
from spherical to deformed nuclear shapes
Radu Budaca (Horia Hulubei National Institute of Physics and Nuclear Engineering), Andreea
Ioana Budaca
A simple exactly separable model for the competition between the γ-rigid and γ-stable collective
motion in the phase transition between spherical and deformed shapes is proposed. The coupling of
the two types of βvibration is achieved by introducing a control parameter measuring the degree
of the systems γ-rigidity in an Ising type Hamiltonian. The separation of variables is achieved by
considering a potential of the form u(β) + u(γ)/β2adapted to the current problem. Matching the
two competing excitations, the γpotential is chosen to be a harmonic oscillator centered in γ= 0,
which is consistent with the prolate γ-rigid part of the problem. While for the βpotential an infinite
square well is considered. The resulting energy spectrum and E2 transition probabilities depend on
two parameters excepting the scale, namely the rigidity and the stiffness of the γvibrations. Their
separate influence on the models characteristics is investigated through numerical applications. The
experimental realization of the model is found in few transitional rare earth nuclei around N= 96.
Collective properties of 170Dy and its nearest neighbors at maximum nucleon
valency
Aila Gengelbach (Uppsala University)
Neutron-rich rare-earth nuclei around the maximum of collectivity are predicted to exist with an
extremely stable intrinsic configuration in their ground-state structure. The present work explores
the structure of the yrast bands in the neutron-rich nuclei 170Dy and 176 Er, which have no previously
known excited states. Nuclear states of 170Dy and 176 Er were populated via the 2p+ 2nand +6n
transfer reactions, respectively. A 860 MeV 136Xe beam was used to bombard a 1.0 mg/cm2thick
self-supporting 170Er target. The experimental setup consisted of AGATA + PRISMA + DANTE.
Beam-like fragments were identified by the PRISMA spectrometer, placed at the grazing angle 44◦.
PRISMA allows for Zand A/q identification, TOF and velocity vector determination, which is
required for the Doppler correction of the emitted γrays detected in time coincidence AGATA.
Additional channel selection based on isomer tagging is possible by using three DANTE detectors
mounted on a 42◦ring. The data analysis is in progress and preliminary results will be presented.

Self-consistent studies of the dipole response in spherical heavy nuclei using
realistic potentials
Frantisek Knapp (Faculty of Mathematics and Physics, Charles University in Prague), Nicola
Lo Iudice, Petr Vesely
The dipole response in neutron rich nuclei is investigated within the equations of motion phonon
method (EMPM) [1]. The approach is fully self-consistent and makes direct use of the chiral po-
tential, optimized up to-next-to-next leading order so as to minimize the effect of three-body forces
[2]. Calculations in Hartree-Fock-Bogoliubov (HFB) plus Tamm-Dancoff (TDA) and random-phase
(RPA) approximations have shown that the potential yields more realistic single particle spectra com-
pared to other potentials and improves the description of the dipole response [3]. TDA and RPA,
however, were unable to describe the finne structure of the giant and Pygmy resonances. To this
purpose a calculation for 132Sn and 208 Pb was performed within EMPM using a space which includes
up two-phonon basis states. These states induce a strong fragmentation of the dipole strength. At
low energy, a large number of weakly excited levels coexist with few strong excitations around the
neutron decay threshold. These levels are excited by both isoscalar and isovector probes and, there-
fore, seem to be the analogue of the spectra detected in (γ , γ0)and (α, α0)in neutron rich nuclei.
The study confirms the crucial role of the two-phonon states in damping GDR and in enhancing the
level density of the low-energy region as recent experiments require.

Interplay between pairing and quadrupole interactions in the microscopic shell
model
Ana Georgieva (Institute of Solid State Physics, Bulgarian Academy of Sciences), Kalin Drumev
We explore the symmetry adapted Pairing-Plus-Quadrupole Model /PQM/ in the framework of the
Elliott‘s SU (3) Model, with the aim to obtain the complementary and competing features of the
pairing and quadrupole interactions in the model Hamiltonian, containing both of them as limiting
cases. We establish a correspondence between the SO(8) pairing basis and the Elliott’s SU (3) basis,
that describes collective rotation of nuclear systems with quadrupole deformation. It is derived from
their complementarity to the same LS coupling chain of the shell model number conserving algebra.
Examples of complete classification of the basis states of different number of particles in both limiting
cases with their correspondence are given for some of the light shells. The probability distribution of
the SU (3) basis states within the SO(8) pairing states is also obtained through a numerical diago-
nalisation of the PQM Hamiltonian. In an application of the model for the description of the 20 Ne
spectra, we investigate systematically the relative strengths of dynamically symmetric quadrupole-
quadrupole interaction with the isoscalar, isovector and total pairing interactions by introducing a
control parameter. In the case of considering all the three types of interactions 2 control parameters
are considered. These parameters define the phase diagram of the model and the role of each term
of the Hamiltonian in the correct reproduction of the experimental data for the considered nuclei.
The approach allows for an extension of the model space for two oscillator shells and introduction of
more elaborate pairing interaction.

The single- and multi-nucleon transfer reactions, namely, 206Pb(18O, x); x= 19 O, 17O, 20 O, 16O,
18N, 17 N, 16N, 15 N, 14N, 16 C, 15C, 14 C, 13C, 12 C, 12B, 11 B, 10B, 10 Be and 9Be have been studied at
an incident 18O energy of 139 MeV. Reaction channels involving transfer of up to nine nucleons have
been detected. Total kinetic energy loss spectrum and angular distribution of cross sections have
been measured. The Q-value and angle integrated cross sections are deduced. Elastic scattering
angular distributions have also been measured and are analyzed by optical model program SFRESCO.
Fully microscopic Time Dependent Hartree-Fock (TDHF) model calculations, based on independent
single nucleon transfer mode, have been carried out and are compared with the experimental data
of multi-nucleon transfer reactions. The TDHF calculations give a reasonably good agreement with
the measurement for few nucleon transfer process, however, the theory becomes less accurate as
the number of nucleons transferred increases. An attempt has been made to include effects due
to particle evaporation in the production cross section by employing a statistical model calculation.
Inclusion of evaporation effects gives some improvements towards the measurement, however, the
calculations still under predict the measured cross section by a significant amount especially for the
cases where a large number of nucleons transferred are involved. Possible origin of these discrepancies

Proton-neutron pairing and quartet condensation in nuclei
Nicolae Sandulescu (National Institute of Physics and Nuclear Engineering, Bucharest, Roma-
nia), Daniel Negrea, Calvin W Johnson
The common treatment of proton-neutron pairing in N∼
=Znuclei relies on Cooper pairs and BCS-
type models. However, the nuclear interaction can induce, through the isospin conservation, quartet
correlations of alpha type which might compete with the Cooper pairs. In fact, for any isovector
pairing interactions the ground state of N=Zsystems is accurately described not by Cooper pairs
but in terms of collective quartets [1]. Cooper pairs and quartets can however coexist in systems
with N > Z. In this case the ground state of the isovector pairing Hamiltonian can be described
with high precision as a condensate of alpha-like quartets to which it is appended a condensate of
neutron pairs [2,3]. Quartets appear to be the relevant degrees of freedom for treating not only the
isovector pairing but also the competition between the isoscalar and the isovector proton-neutron
pairing in N=Znuclei [4,5]. These facts indicate that the many-body pairing problem in N∼
=Z
nuclei can be more efficiently treated in calculation schemes based on alpha-type quartets rather
than on Cooper pairs and BCS-type models.

Origin of low-lying enhanced E1 strength in rare-earth nuclei
Mark-Christoph Spieker (University of Cologne), Andreas Zilges, Sorin Pascu
Candidates for excited alpha-cluster states have been identified in many light nuclei being organized
in rather simple quasi-molecular configurations [1]. For heavier nuclei the existence of these states
remains an open question, though different experimental observables have been discussed as possible
signatures. The electric dipole response of atomic nuclei is intimately connected to the breaking of
isospin symmetry in simplified macroscopic nuclear models. Here, an alpha-cluster could oscillate
against the remaining core, which would generate a dynamic electric dipole moment in the nucleus
[2]. To study this possibility, we have adopted the spdf interacting boson model for the description of
the experimental E1 response below 4 MeV in the neodymium isotopes and other rare-earth nuclei,
which was obtained by means of systematic (γ, γ0)experiments [3]. In this contribution, we will
show that the model successfully reproduces the main features of the experimental E1 response
and, thus, might establish alpha-clusters as an important ingredient to describe the E1 strength
distribution in heavier nuclei. This work is supported by the DFG (ZI-510/4-2). M.S. is supported
by the Bonn-Cologne Graduate School of Physics and Astronomy.

How evident is the shape coexistence phenomenon in the lead region?
Jose-Enrique Garcia-Ramos (University of Huelva), Kris Heyde
The lead region is considered as a paradigm of the shape coexistence phenomenon and several decades
of experimental effort have supported this believe. In particular, long chains of the Pb, Hg, Pt and Po
isotopes have been measured and a rich experimental body of data concerning excitation energies,
electromagnetic transition rates, radii, magnetic g-factors, alpha-hindrance factors and Coulomb
excitation reactions, has been obtained [1]. In the case of Pb and Hg, the presence of intruder
states is self-evident inspecting the parabolic energy systematics of the intruder states. However,
however in the case of Pt and Po, the presence and influence of intruder states is not obvious. In this
contribution, we try to clarify the situation using a set of Interacting Boson Model calculations that
we carried out during the last few years [2]. We show that in order to understand the systematics
of the large set of observables in this mass region, we can resort to simple arguments based on the
strength of the interaction between regular and intruder configurations, and, moreover, on the energy
difference between both types of configurations.

Structure of N=Znuclei in single j shell calculations
Kai Neerg˚ard (Naestved, Denmark)
I discuss calculations of states with angular momentum zero in nuclei with equal numbers of neutrons
and protons and either four or eight nucleons or nucleon holes in the 1f7/2or 1g9/2shell with effective
interactions from the literature. Consistently and fairly independently of the interaction, the ground
states have by about 75% seniority zero in Flowerss classification of states in a single j shell by a
seniority and a reduced isospin. This structure may be seen as the manifestation of isovector pairing
in this model. The rest of the ground state configuration has entirely or almost entirely seniority two
and reduced isospin zero. Configurations constructed from pairs of a neutron or neutron hole and a
proton or proton hole aligned to the maximal angular momentum have overlaps of 25%-62% with the
seniority zero state. This illustrates that the Pauli principle prohibits a perception of isovector and
isoscalar pairings as being mutually exclusive. The states with aligned neutron-proton pairs largely
select by projection the components of the calculated ground states from multidimensional spaces
with a given seniority and reduced isospin zero. By calculating the binding energy as a function of
isospin with modified interactions where certain components are omitted, one finds that - contrary
to suggestions in the literature - the isoscalar interactions are responsible for the symmetry energy
rather than the Wigner energy.

Dipole toroidal resonance: vortical properties, deformation impact, relation
to pygmy mode
Valentin Nesterenko (Joint Institute for Nuclear Research, Dubna)
Properties of the isoscalar dipole toroidal resonance (TR) in spherical and deformed nuclei are dis-
cussed using our recent results obtained within the self-consistent random phase approximation with
Skyrme forces [1-4]. The TR strength functions, transition densities and velocity fields are inspected.
The resonance is compared to other exotic isoscalar dipole modes (compression and pygmy) [1,2].
The main attention is paid to: i) possibility to use TR as a measure of the nuclear vorticity [3], ii)
anomalous TR deformation splitting [4], iii) relation of the TR and pygmy dipole resonance [2], iv)
perspectives of experimental observation of the TR.

Lifetime measurements to study shell evolution beyond N= 50
Andrea Gottardo (IPN Orsay), David Verney
Recent experimental discoveries have revealed that the neutron effective single particle evolution
above 78 Ni shows peculiar behaviours. The neutron monopole drifts towards 78Ni remain an open
and urgent question and the light odd-neutron N= 51 nuclei (towards 78Ni) constitute the most
interesting cases to study this evolution. Low-lying states in N= 51 isotones may naturally be
understood in terms of single-particle configurations and core-particle coupled (collective) states.
Both structures were historically well identified in 89Sr Z= 38,N= 51) which can be considered as
a reference nucleus. The aim of the experiment was to determine the nature of the low-lying Yrast
or quasi Yrast states in 83 Ge (Z= 32) in order to assess their collective (shorter lived) or single-
particle (longer lived) origin and disentangle monopole drift effects from the rest of the structure
evolution towards 78Ni core. Calculations and systematics show that there is a difference of about
two orders of magnitude between core-particle coupled state (shorter lived) and single-particle state
(longer lived) half lives. The relevant nuclei were produced via a fusion-fission reaction with a 238U
beam at 6.2 MeV/u energy impinging on a Be target. The beam current was around 0.5 pnA. The
Recoil Distance Doppler-Shift method was employed using the OUPS plunger, with three degrader
positions. The gamma rays were detected by the AGATA array in coincidence with the VAMOS mass
spectrometer. The half lives of several states of interest were measured and preliminary results will
be presented.
Interacting Boson Approximation (IBA-1) determinations for reduced transi-
tion probabilities of 152 ≤A≤248 nuclei
Sardool Singh Ghumman (Sant Longowal institute of engg. and tech.-deemed university, Lon-
gowal, India)
The theoretical B(E2) ratios have been calculated on DF, DR and Krutov models. A simple method
based on the work of Arima and Iachello is used to calculate the reduced transition probabilities
within SU (3) limit of IBA-I framework. The reduced E2 transition probability ratios of 2-γ/2-ground
to 2-γ/0-ground from second excited states of rare-earths and actinide eveneven nuclei calculated
from experimental energies and intensities from recent data compare better with those calculated on
the Krutov model and the SU(3) limit of IBA than the DR and DF models.

A microscopic derivation of nuclear collective rotation-vibration model
Parviz Gulshani (NUTECH Services)
We derive a microscopic version of the successful phenomenological hydrodynamic model of Bohr-
Davydov-Faessler-Greiner for collective rotation-vibration motion of an axially symmetric deformed
nucleus. The derivation is not limited to small oscillation amplitude. The nuclear Schrodinger equa-
tion is canonically transformed to collective co-ordinates, which is then linearized using a constrained
variational method. The associated constraints are imposed on the wavefunction rather than on the
particle co-ordinates. The approach yields three self-consistent, time-reversal invariant, cranking-
type Schrodinger equations for the rotation-vibration and intrinsic motions, and a self-consistency
equation. For harmonic oscillator mean-field potentials, these equations are solved in closed forms
for excitation energy, cut-off angular momentum, and other nuclear properties for the ground-state
rotational band in deformed nuclei. The results are compared with measured data.
Anomalies of transition probabilities in even-even nuclei in medium mass re-
gion: a challenge for nuclear models
Satendra Sharma (Department of physics, Yobe state university, Damaturu, Yobe State, Nigeria)
The experimental data [1] has been compiled for B(E2; 4g→2g)/B(E2; 2g→0g)branching ratio
for even even nuclei of medium mass region. The anomalies have been observed for some non-
magic nuclei. The systematic study of this branching ratio has been carried out and observed data is
compared with the predictions of SU(5),O(6),SU(3) and X(5) limits of interacting boson model
(IBM)[2] and asymmetric rotor model (ARM)[3]. It is noted the IBM is successful in explaining
the anomalies in the observed transition probabilities. However, the ARM is partially successful in
explaining this branching ratio. The Z= 64 subshell effect is also seen for N≤90 region.

A characteristic study of the most probable nucleus beyond the island of
stability
S. Santhosh Kumar (Depart. of Physics, Bharathidasan Govt. College for Women, Puducherry,
India), P. Preetha, A. Victor Babu
The possible occurrence of superheavy nuclei(SHN) in nature, neutron stars, pallasite meteorites
validated the theoretical predictions about the occurrence of SHN in nature. Very recently, Zagrebaev
et al. estimated the possibility of production of SHN in the astrophysical rprocess. Ohnishi and
Okamoto has studied the nuclear structure properties of neutron magic numbers 184, 228 and 308
and proton magic number 114 and 164, and reported that the upper mass limit of the rprocess
depends strongly on the magic neutron numbers. In this work the expected next proton magic
number Z= 164 in the next island of hyperheavy nuclei is studied. BE/A through the Droplet
model (Z= 164 and N= 180 −390 suggests the maximum binding is from N= 250 −270
(>6.1MeV). But the positive p and n for N= 184, suggests higher probability of existence of
348164. The multi-nucleon separation energies are obtained through BE formalism. The single
particle levels and the level density and entropy are obtained through cranking and statistical models
resply and the spin cut-off parameter, using our modified formula. The level density increases with
temperature. At T > 1MeV, it became infinite, which shows the nucleus reaching the plasma state.
The survival of 184164 upto T= 1 MeV, suggests that the nuclei beyond the island of stability
will lie along or near to N=Zline. Thus a high possibility of occurrence of hyperheavy nuclei in
supernovae is predicted, since supernovae generally contain material with equal numbers of neutrons
and protons.

Neon MOT experiment for Beta-decay studies
Ben Ohayon (Hebrew University of Jerusalem), Guy Ron
In this talk, I will review the current status and future outlook of NeAT - the Neon Atom Trap Setup
at the Hebrew university. We are developing a highly efficient atomic trap setup for different isotopes
of metastable neon for the purpose of conducting high precision experiments in atomic and nuclear
physics. Modern experiments with neutral atoms trapped using modern laser-cooling techniques
offer the promise of improving several broad classes of experiments with radioactive isotopes [1]. For
nuclear beta-decay, precise measurements of the kinematic correlations between the emitted positron
and neutrino test the standard model of the weak interaction [2]. These correlations are sensitive to
scalar- and tensor-current interactions which are suggested by some beyond standard model theories
[3], and high statistics measurements of them put strict limitations on their parameter space.

The large scale facility Extreme Light Infrastructure - Nuclear Physics (ELI-NP) [1], currently under
development, is the one of the three pillars of the Extreme Light Infrastructure Pan-European initia-
tive which is dedicated to nuclear physics with extreme electromagnetic fields. A high power laser
system and a very brilliant gamma beam are the main research equipment at the core of ELI-NP.
The gamma beam system (GBS) will produce through laser Compton scattering highly polarized (>
99%), energy tunable γ-ray beams with spectral density of 104photons/s/eV, ranging from 200 keV
to 19.5 MeV and with a bandwidth better than 0.5%. Using the brilliant GBS at ELI-NP, we propose
to investigate the excitation, and particle and gamma decay of Giant Resonances. We plan to develop
a multipurpose neutron and gamma radiation detection setup consisting in a flexible array of large
volume scintillator detectors and liquid scintillation neutron detectors. We present here the results of
Geant4 simulations of this array and also the challenges raised by the gamma beam time structure.

Design and simulations of the source of polarized slow positrons at ELI-NP
Nikolay Djourelov (Extreme Light Infrastructure - Nuclear Physics Horia Hulubei National In-

We present the status of simulations to obtain an intense beam of moderated positrons (e+
s) with an
intensity of the primary positron beam of 1−2×106e+
s/s by the (γ,e+e−) reaction, using an intenseγ
beam of 2.4×1010 γ/s with energies up to 3.5 MeV. Using fully circularly polarizedγbeam we aim
to obtain an intense beam of slow polarized positrons with a polarization degree of 31-45%. The
beam will be transported to different detector systems through beam lines, via solenoidal magnetic
fields. In applied physics studies of Fermi-surfaces, defects, interfaces etc. positrons offer excellent
diagnostics tools. Furthermore, polarized positron beams open up a totally unexplored research area,
where polarized electrons in, e.g., magnetic structures can be studied. A simple, fast scintillator
detector system for gamma-induced positron annihilation lifetime spectroscopy for studies of bulk
samples is also proposed. The positron spectroscopy laboratory at ELI-NP will be user-dedicated and
unique for positron research in the Eastern Europe. It will provide a simple source setup, with easy
access for upgrade of the converter/moderator assembly toward more sophisticated setups providing
a more intense and brighter positron beam. The beam will have the world highest intensity of slow
polarized positrons for material science studies and therefore it will become a unique tool for the
investigation of magnetic samples.

The Extreme Light Infrastructure Nuclear Physics (ELI-NP) facility will come online in Bucharest-
Magurele, Romania in 2017 and will consist of two components: a very high intensity laser and
a very intense gamma beam. ELI-NP will allow either combined or stand-alone experiments using
the high-power laser and the gamma beam. The high brilliance Gamma Beam System (GBS) at
ELINP will deliver quasimonochromatic gamma-ray beams (bandwidth <0.5%) with a high spectral
density (>10000 photons/s/eV) and high degree of linear polarization (>99%). The GBS will be
delivered in two phases with two separate beam lines: a low-energy gamma-ray line with gamma
energies up to 3.5 MeV and a high-energy gamma line with energies up to 19.5 MeV. Optimization
and monitoring of the gamma beam with these characteristics is challenging and requires the proper
means for accurately measuring the spatial, spectral and temporal characteristics of the gamma-ray
beams. The gamma beam energy spread will be monitored using a large volume HPGe detector with
anti-Compton shield placed in an attenuated beam. An intensity and polarization monitor is pro-
posed based on the d(γ, n)reaction which could be placed in either the low-energy or the high-energy
experimental areas. Several additional instruments using Compton scattering and photo-fission are
envisioned for measuring the time structure, intensity, and polarization of the beam. Preliminary
conceptual designs of these devices will be presented.

One of the most important parameter of ADS experimental setups is a neutron flux density of the
secondary neutron field. The flux can be experimentally determined using activation detectors like
59Co. The experiment with 59 Co was performed at Joint Institute for Nuclear Research, Dubna,
Russia in December 2013. The field of secondary neutrons was generated at the massive natural
uranium spallation target QUINTA. The QUINTA assembly was irradiated with deuteron and car-
bon beams at the Nuclotron accelerator. Energy of particles was 4 AGeV for deuteron beam and
2 AGeV for 12C. The samples of 59Co were irradiated in the field of secondary neutrons. Samples
were square-shaped. A total of 10 experimental samples were situated in different positions inside
the target QUINTA. The setup is composed of five hexagonal sections. The total mass of natural
uranium is 512 kg. The uranium is situated in aluminium rods. After irradiation, the samples were
transported to the YaSNAPP spectroscopy laboratory. In the laboratory, the samples were measured
with the use of HPGe semiconductor detectors. Reaction rates were determined for residual nuclei
in cobalt samples. Reaction rates from deuteron beam irradiation were compared with reaction rates
from 12C beam irradiation. Experimental values were also compared with calculated values using
the MCNPX and TALYS 1.6 codes. The neutron flux was determined using the experimental results
of (n, xn)and (n, p)reactions. The experimentally determined neutron flux was compared with
simulations. The comparisons have a good agreement.

EXL (EXotic nuclei studied in Light-ion induced reactions at storage rings) is a project within NUS-
TAR at FAIR. It aims for the investigation of light-ion induced direct reactions in inverse kinematics
with radioactive ions in storage rings at the future FAIR facility. One of the key interests of EXL
is the investigation of reactions at very low momentum transfers where, for example, the nuclear
matter distribution, giant monopole resonances (GMR) or Gamow-Teller transitions can be studied.
The existing ESR at GSI, together with its internal gas-jet target, provides the unique opportunity
to perform this kind of experiments on a smaller scale already today. We have developed a UHV
compatible detector setup mainly based on DSSDs for the target-like recoils and an in-ring detection
system for the projectile-like heavy ions. With this setup we successfully investigated reactions with
a stored radioactive beam for the very first time. As a part of the first EXL campaign we investigated
the reaction 56Ni(p, p)56 Ni in order to measure the differential cross section for elastic proton scatter-
ing and deduce the nuclear matter distribution and the radius of 56Ni. Furthermore, as a feasibility
study, we excited the GMR of 58Ni by utilizing the 58Ni(α, α0)58 Ni reaction. This contribution will

The electromagnetic calorimeter of the PANDA detector at FAIR
Malte Albrecht (Bochum), PANDA Collaboration
The versatile 4π-detector PANDA will be built at the Facility for Antiproton and Ion Research
(FAIR), an accelerator complex, currently under construction near Darmstadt, Germany. A cooled
antiproton beam in a momentum range of 1.5 15 GeV/cwill be provided by the High Energy Storage
Ring (HESR). All measurements at PANDA rely on an excellent performance of the detector with
respect to tracking, particle identification and energy measurement. The electromagnetic calorimeter
(EMC) of the PANDA detector will be equipped with 15808 PbWO4crystals (PWO-II), which will
be operated at a temperature of 25◦C in order to increase the light output. In this talk especially the
design of the forward endcap of the EMC will be shown. The crystals in this detector part will be
read out with Large Area Avalanche Photo Diodes (LAAPDs) in the outer regions and with Vacuum
Photo Tetrodes (VPTTs) in the innermost part. Production of photosensor units utilizing charge
integrating preamplifiers has begun. A prototype comprised of 216 PbWO4crystals has been built
and tested at various accelerators (CERN SPS, ELSA/Bonn, MAMI/Mainz), where the crystals have
been exposed to electron and photon beams of 25 MeV up to 15 GeV. The results of these test
measurements regarding the energy and position resolution are presented. This work is supported by

The new readout concept of the PANDA experiment
Marcel Tiemens (KVI-CART (University of Groningen)), PANDA Collaboration
One of the physics highlights of the future PANDA experiment at the Facility for Antiproton and Ion
Research (FAIR, currently under construction) is to search for exotic states that have been predicted
by Quantum Chromodynamics, and whose properties are governed by the presence of valence gluons.
Such exotic states can be formed directly and copiously in proton/antiproton annihilations, which
will be colliding at centreofmass energies between 2.5 and 5.47 GeV in PANDA. The challenge lies
in reducing the enormous background yield, while preserving a high efficiency for the detection of
exotic hadrons. As the detector response for background events is very similar to that for the decay
of the exotic states, the use of a conventional triggered readout scheme, where a limited number of
subdetectors generates a trigger signal that engages the readout of the complete detector, is ruled
out. Therefore, a new type of intelligent readout is being developed, where kinematic constraints
are imposed in realtime on online reconstructed events. As this no longer relies on the use of a
trigger, this concept is called a triggerless readout system. Another challenge lies in handeling the 20
MHz interaction rate, which can cause detector response signals to overlap. These socalled pileup
signals will require special treatment by the readout system. To illustrate how the implementation is
envisioned, the concept of the triggerless readout system, along with its current status and simulation
will be discussed for one of the subdetectors, the Electromagnetic Calorimeter.
Measurement of the spatial and energy-loss resolution with a prototype Straw
Tube Tracker (STT) for the PANDA experiment
Alexandros Apostolou (KVI-CART/University of Groningen, FZJ), PANDA Collaboration
The PANDA experiment is one of the pillars of the future Facility for Antiproton and Ion Research
(FAIR) in Darmstadt, Germany. The PANDA physics program is focused on answering fundamental
questions re- lated to Quantum Chromodynamics (QCD), mostly in the non-perturbative energy
regime, using antiproton collisions on proton and nucleon targets. The central Straw Tube Tracker
(STT) will be the main tracking detector of the PANDA target spectrometer. The main tasks of
the STT will be the measurement of the particle momentum from the reconstructed tracks (with a
spatial resolution '150 µm transversal) and the measurement of the specific energy-loss for particle
identification (with an energy resolution better than 10%), especially for particles with momenta
below 1 GeV/c. In this work, results obtained with a prototype STT using a proton beam with
different momenta are shown and discussed, with an emphasis to the spatial resolution and the
energy-loss for the different momenta.

The Super FRagment Separator (Super-FRS) at the FAIR facility will be the largest in-flight separator
of heavy ions in the world. The separation principle is based on the use of beam collimators to stop
the unwanted ions. In one of the most common situations, the heavy ions are produced by a fission
reaction of a primary 238U beam (1.5 GeV/u) hitting a 12C target. In this situation, some of the
produced ions are highly charged states of 238U. Those ions can reach the collimators with energies of
up to 1.3 GeV/u and a power of up to 500 W. Under these conditions, a cooling system is required
to prevent damage to the collimators and to the corresponding electronics. Due to the highly
radioactive environment, both the collimators and the cooling system must be suitable for robot
handling. Therefore, an active cooling system is undesirable because of the increased possibility
of malfunctioning and other complications. By using thermal simulations (performed with NX9 of
Siemens PLM), the possibility of passive cooling is explored. The validity of these simulations is
tested by independent comparison with other simulation programs and by experimental verification.
With this validation, reasonable estimates can be made on the true effectiveness of passive cooling of
the beam collimators. This information is used to ensure stable and safe operation of the Super-FRS
beam collimators. Some results and conclusions will be presented in this contribution.

At the Low-Energy Branch of the Super-FRS, projectile and fission fragments will be produced at
relativistic energies, separated in-flight, energy-bunched, slowed down and then thermalized in a
cryogenic stopping cell (CSC) filled with ultra-pure helium gas. After extraction from the CSC the
ions will be delivered to the high precision experiments MATS andLaSpec. The prototype of the
CSC and the multiple-reflection time-of-flight mass spectrometer (MR-TOF-MS), part of the MATS
experiment, has been tested at the FRS Ion Catcher experiments with heavy uranium projectile frag-
ments and fission fragments produced at 1000 MeV/u at GSI. Thermalized inos are identified and
measured using alpha-spectroscopy and precision mass measurements in the MR-TOF-MS. A new
record was achieved for the areal density of stopping cells operated with beam (6.3 mg/cm2), a
factor of three larger than for any other stopping cell with RF structures with extraction efficiencies
in excess of 60%. First direct mass measurements of several nuclides using the MR-TOF-MS at
mass resolving powers of up to 400,000 were performed. Access to rare (few detected ions per hour)
and very short-lived (half-lives of a few milliseconds) nuclides was demonstrated. The measurement
of isomeric states with an MR-TOF-MS as isomer separator was demonstrated for the first time,
thusopen up a unique perspective for isomer-resolved studies. Results from the online experiments
and the design of final CSC will be presented and discussed in detail.

A new technique to produce and study the most exotic neutron-rich nuclei
Andrea Gottardo (Laboratori Nazionali di Legnaro, Istituto Nazionale di Fisica Nucleare), Jo-
nathan Wilson, Matthieu Lebois, Liqiang Qi
We have recently successfully demonstrated a new technique for production and study of many of
the most exotic neutron-rich nuclei. LICORNE, a newly developed directional inverse-kinematic fast
neutron source at the IPN Orsay, was coupled to the Miniball high resolution gamma ray spectrometer
to study nuclei the furthest from stability using the 238U(n,f) reaction. This reaction is the most
neutron-rich fission production mechanism achievable and was employed to simultaneously populate
hundreds of neutron-rich nuclei up to spins of 16h. High selectivity in the experiment was achieved
via the use of a 400 ns period pulsed neutron beam, a technique which is unavailable to other
population mechanisms such as 235 U(nth, f)and 252Cf(SF) used in the past. The pulsing allows
time correlations to be exploited to separate delayed gamma rays from isomeric states in the hundreds
of nuclei produced which are then used to cleanly select a particular nucleus and its exotic binary
partners. The most interesting cases occur when the isomeric state is in a nucleus close to stability
(e.g. 130Te), which guarantees from mass/charge conservation that the binary partners (106,108Zr)
are at/beyond the very limit of our present knowledge. In the recent experiment several physics
cases are simultaneously addressed such as shape coexistence, the evolution of the shell closures near
doubly-magic 78Ni, and the spectroscopy of nuclei in the rprocess path near N= 82. Preliminary
results will be presented.
Rapid light manipulation techniques for collinear laser spectroscopy in appli-
cation for neutron-deficient francium
A. Voss (University of Jyv¨askyl¨a)
Collinear laser spectroscopy has been the workhorse at radioactive beam facilities to study nuclear
spins, electromagnetic moments and changes in mean-squared charge radii for decades. With the
quest of proceeding towards the study of more exotic isotopes, rapid light manipulation techniques
for narrow-linewidth lasers have been developed in order to reduce the hyperfine pumping associated
with fluorescence studies of atomic species. Firstly, the laser intensity supplied to the spectroscopy
setup is modulated by means of an electro-optical modulator acting as a fast-switching half-waveplate
[1]. Generating individual photon pulses and thus effectively achieving an on/off effect for the laser
light, the observed intensities for the weaker hyperfine transitions are dramatically increased. The
reduction of hyperfine pumping effects has aided in nuclear structure studies of francium [1] and
rubidium [2] isotopes and isomers. Secondly, the intensity modulation technique has been taken
further by implementing rapid frequency switching using a double-pass, acousto-optical modulator
[3]. The synchronisation of the two modulators allows short photon bursts at variable frequencies to
be delivered to the light collection region allowing for an increase of the total laser/atom interaction
time whilst maintaining minimal hyperfine pumping. In this contribution, a detailed description of the
new developed techniques and results from the experiment at TRIUMF-ISAC on neutron-deficient
francium isotopes and isomers will be presented.

Study of excited ηmesons in photoproduction at CLAS
Cathrina Sowa (Ruhr Universit¨at Bochum)
The CLAS experiment at CEBAF at Jefferson Laboratory investigates photon scattering on the proton
with high intensities. The analysis presented in this talk focuses on the reaction γp →pπ +πη to
investigate excitations of ηmesons. The observed ηas well as the η(1295) and η(1405) decay
preferably to π+πη. The main goal is to improve the present knowledge of these states. Based
on SU (3) symmetry for the light mesons a singlet as well as an octet is formed. Each contains one
isoscalar state which mix to the lightest pseudoscalar mesons ηand η. Thus two rst radial excitations
are expected, but three states were found: η(1295),η(1405) and η(1475). The η(1405) is debated to
be a gluonic bound state, because it has been observed in gluon rich production mechanisms only. In
this scenario the η(1405) should have a low production cross sections in γγ fusion or photoproduction.
We report on the measurement of ηand η(1405) production cross section in γp →pπ +πη.
Electroproduction of f0(980) and f2(1270) with CLAS detector
Brice Garillon (IPN Orsay)
The Quark Model has predicteDmeson spectroscopy with great success. However, the nature of
some light unflavoreDmesons is not fully determined yet. The case of f0(980) is particularly puzzling.
Its nature remains debatable: it may be a 4-quark state or a KK molecule, rather than a simple
q−¯qpair. While f2(1270) is better known, there are suggestions that it could be an intermediate
state generated by vector meson-vector meson interactions. The electroproduction of the f0and f2
(ep →epf0/f2) have never been measured so far, and may shed light on their structure. In this
work, cross sections for the electroproduction of f0and f2have been extracted in the dominant
decay channel ep →epπ+π−, using data taken at Jefferson Lab with the CLAS detector. In addition
to these measurements, a Partial Waves Analysis of the epπ+π−final state is under study. Such
technique provides the decomposition of a mass spectrum according to the angular distribution of
the decay products, allowing a clearer identification of meson resonances of different spin.
The η-meson decay program at WASA-at-COSY
Daniel Lersch (J¨ulich Research Center Germany), WASA-at-COSY Collaboration
The study of η-decays allows to probe symmetry-breaking phenomena, to test theoretical calculations
and to explore the anomalous sector of QCD. In order to perform those studies two data samples
have been acquired with the WASA-at-COSY facility at Forschungszentrum J¨ulich. A proton beam
is accelerated within the COSY storage ring towards a liquid deuterium or a liquid hydrogen pellet
target producing η-mesons via: pd→3Heηor pp →ppη. The η-decay products as well as the
forward-scattered projectiles are detected within the 4πWASA-at-COSY detector. A first round of
experiments was done with the pd→3Heηreaction used for the study of the more abundant η-decay
channels and to set up the framework for a common analysis. In order to address the rare η-decays
a high-statistics data set has been collected in the reaction pp →ppη. The current analysis of the
pp →ppη data set is related to the following decay modes of the η-meson: η→π+π−π0is isospin
violating and allows to probe quark masses. η→e+e−γand η→e+e−e+e−serve to determine the
electromagnetic transition form factor. C-violation can be tested via η→π0e+e−. The radiative
decay η→π+π−γis sensitive to the box anomaly. This talk will give an overview about the status
of the analyses.

Measurement of polarization observables in neutral double pion photoproduc-
tion off the proton with the CBELSA/TAPS-experiment
Tobias Seifen (HISKP, Uni Bonn), CBELSA/TAPS Collaboration
One important step in understanding the baryon spectrum is a precise knowledge of the excited
states and their decays. In order to extract the contributing resonances from experimental data a
partial wave analysis needs to be performed. To resolve ambiguities, the measurement of polariza-
tion observables is indispensable. In the regime of high mass baryon resonances multi-meson final
states are of particular importance. Here sequential decays of resonances are observed. The Crystal
Barrel/TAPS experiment is ideally suited to measure the photoproduction of neutral mesons decay-
ing into photons due to its good energy resolution, high detection efficiency for photons, and the
nearly complete solid angle coverage. In combination with a longitudinally or transversely polarized
target and an energy tagged, linearly or circularly polarized photon beam the experiment allows the
measurement of a large set of polarization observables. This talk will focus on preliminary results of
neutral double pion production obtained with a transversely polarized target. This work is supported
by the DFG (SFB/TR16).
Light meson spectroscopy at BESIII
Marc Pelizaeus (Ruhr-Uni Bochum), BESIII Collaboration
The BESIII experiment has accumulated a large sample of J/ψ,ψ(2S)and ψ(3770) data set.
Through these charmonium radiative and hadronic decays, we can explore the light hadron spectro-
scopies. In this talk, we will report our recent results on the properties of the Xstates, such as
X(1835) and X(p¯p), study of J/ψ radiative decays (J/ψ →γKKη ,γπ+π−η0,γπ0π0). In addition,
we also present our results on the decays of light mesons ηand η0at BESIII.
Recent results from the COMPASS experiment
Johannes Bernhard (CERN), Tobias Weisrock
The goal of the COMPASS experiment at CERN is to study the structure and dynamics of hadrons.
The two-stage spectrometer has a good acceptance over a wide kinematic range for charged as well
as neutral particles and thus allows to access a large range of reactions. Light mesons are studied
with negative (mostly π−) and positive (p, π+)hadron beams with a momentum of 190 GeV/c. The
spectrum of light mesons is studied in diffractive reactions of those beams on a liquid hydrogen target
with a four-momentum transfer between 0.1 and 1.0 GeV2/c2. In the π−π−π+channel COMPASS
has recorded the currently largest data set. Using novel analysis methods, these data not only allow
to measure the properties of known resonances with high precision, but also to search for new states.
Among these is a new axial-vector meson with a mass of 1.4 GeV/c2. Findings in the π−π−π+
channel are supplemented by the π−π0π0final state. Additional insight is gained from channels with
ηor η0in the final-state, or centrally produced systems. The structure of light mesons is studied with
a negative pion beam scattering off solid targets, either lead or nickel. Primakoff reactions at low
momentum transfers allow to determine the polarisability of the pion, and thus to test predictions by
chiral perturbation theory. Additionally, these reactions are used to determine the radiative widths
of a2(1320) and π2(1670).

Partial Wave Analyses of antiproton-proton annihilations in flight
Julian Pychy (Ruhr-Universit¨at Bochum(RUB)), Helmut Koch, Bertram Kopf, Ulrich Wiedner
To investigate important aspects for the upcoming PANDA experiment, partial wave analyses (PWA)
of antiproton-proton annihilation processes are carried out using data from the Crystal Barrel (LEAR)
experiment. A coupled channel analysis of the three reactions resulting in the final states K+K−π0,
π0π0ηand π0ηη at a beam momentum of 900 MeV/cis currently in progress. Preliminary results on
the determination of resonance contributions and of the spin density matrix (SDM) of different light
mesons are presented. The elements of the SDM provide important information about the production
process. Furthermore, results of analyses of the ωmeson in different channels are discussed. These
studies are focused on the determination of the contributing angular momenta of the antiproton-
proton system as well as of the SDM of the ω. Significant spin-alignment effects depending on
the production angle are visible here. All analyses have been performed using PAWIAN, a com-
mon, object-oriented and easy-to-use PWA software that is being developed at the Ruhr-Universit¨at
Bochum. This presentation summarizes recent activities of the Crystal Barrel (LEAR) Collaboration.

Dilepton production in pion induced reactions
Gyorgy Wolf (Hungarian Academy of Sciences(KFKI-RMKI)), Mikl´os Z´et´enyi
We calculate electron-positron pair production in pion-nucleon and pion-nucleus collisions. We derive
the elementary cross sections in an effective field theory approach. We use these cross sections in a
transport model to study π−nucleus reactions. We study the effect of the interference term (which
is destructive in π+nand constructive in π−pcollisions) of the ρand ωmesons on the dilepton
spectra in π+Aand π−Acollisions. Due to the interference term the ration of the cross sections at
the omega mass is 4. This ration is reduced to 2 for heavy target because secondary reactions reduce
the interference. Therefore, pion induced dilepton production allow us to study the decoherence in
a strongly interacting medium.

Employing spin symmetry to disentangle different models for the XYZ states
Martin Cleven (Institute of High Energy Physics and Theoretical Physics Center for Science Fa-
cilities, Chinese Academy of Sciences, Beijing 100049, China), Qian Wang, Christoph Hanhart,
Feng-Kun Guo, Qiang Zhao
In order to test different models proposed for some states discovered recently in the charmonium
mass range that do not fit into the pattern predicted by the conventional quark model, we derive
predictions for the spectrum within the hadro-charmonium picture, the tetraquark picture as well as
the hadronic molecular approach. We exploit heavy quark spin symmetry for the hadro-charmonium
and hadronic molecule scenarios. The patterns that emerge from the different models turn out to be
quite distinct. For example, only within the hadro-charmonium picture a pseudoscalar state emerges
that is lighter than the Y(4260). Possible discovery channels of these additional states are discussed.
XYZ spectroscopy at BESIII
Landdiao Liu (Peking University), BESIII Collaboration
The BESIII Experiment at the Beijing Electron Positron Collider (BEPC2) collected large data sam-
ples for electron-positron collisions with center-of-mass above 4 GeV during 2013 and 2014. A
number of hadronic transitions have been measured in these data samples, leading to a rather com-
plex picture of the physics of charmonium(-like) states above 4 GeV. In this talk we will present results
for the hadronic and radiative transitions among these states and the four quark state candidats Zcs.
Perspective study of heavy flavour mesons and baryons
Mikhail Barabanov (JINR), Alexander Vodopyanov
The D-meson spectroscopy together with the spectroscopy of charmed and strange baryons is dis-
cussed. A large number of D-mesons produced in pair at the threshold can be used to study rare
processes in the charm system like CP-violation, flavour mixing, rare decays. The expectation from
the standard model is that CP-violation is large for K-system and B-system but small for D-system.
A deviation from this small effect indicating new physics can be thus easier distinguished in the
D-system than in K- and B-systems. Leptonic decays of D- and Ds mesons open the road to under-
standing the hadron structure. They probe quark wave functions and represent themselves as a good
test for lattice QCD. An understanding of the baryon spectrum is one of the primary goals of non-
perturbative QCD. In the nucleon sector, where most of the experimental information is available, the
agreement with quark model predictions is astonishingly small, and situation is even worse in strange
and charmed baryon sector. For this purpose a detailed analysis of spectrum of flavour mesons and
baryons is given. The recent experimental data from different collaborations are analyzed. Many
heavy measons and baryons with charm and strangeness are expected to exist in the framework of
the proposed combined approach. But much more data on different decay modes are needed before
firmer conclusions can be made. These data can be derived directly from the experiments with high
quality antiproton beam with momentum up to 15 GeV/cplanned at FAIR.

Observation of the isovector dibaryon resonance-like state with mass of 2.18
GeV/c2
Dmitry Tsirkov (Joint Institute for Nuclear Research), Vladimir Komarov
The pion production in proton-proton collisions with formation of the final-state 1S0proton pair has
been studied at ANKE-COSY. The angular dependence of the differential cross section has a forward
dip in the whole energy region, its energy dependence reveals a clean peak in the ∆(1232) resonance
region. The analyzing power is found significant, the maximal value of its angular dependence varies
from 0.3 to 0.8 at different energies. A partial wave analysis assuming essential contribution of only
two amplitudes, MPs and MPd, shows a resonance behavior of the D-pion wave amplitude with
Breit-Wigner parameters ER= 2181 ±8MeV/c2and Γ = 108 ±24 MeV/c2. The peak in the
forward cross section energy dependence looks as a direct manifestation of a ∆Nresonance state
in the P-wave of its relative motion. Position of the resonance indicates a strong attractive ∆N
interaction in the JP= 2 state. The S-wave transition amplitude has a value comparable with
the D-wave amplitude and due to interference causes the observed dip in the forward cross section
and significant analyzing power. The S-wave amplitude squared reveals a resonance-like energy
dependence similar to that of the D-wave.
Baryon spectroscopy at BESIII
Xiongfei Wang (Tsinghua University), BESIII Collaboration
The BESIII experiment has accumulated a large sample of J/ψ,ψ(2S)and ψ(3770) data set.
Through these charmonium radiative and hadronic decays, we can explore the light hadron spec-
troscopies. In this talk, we will report our recent results on the study of the baryon spectroscopy.
In addition, BESIII collected 506/pb sample at √s= 4.6GeV, which allows us to perform the
double-tag technique to measure the rates in the model-independent way near threshold for the first
time. Herein, we present our analysis results on branching fractions for 12 Λ+
chadronic decays,
including BF(Λ+

X-rays of light kaonic atoms: SIDDHARTA and future
Michael Cargnelli (Austrian Academy of Sciences - Stefan Meyer Institute), SIDDHARTA Col-
laboration
The X-ray measurements of kaonic atoms are important for understanding the low-energy QCD in
the strangeness sector. Within then SIDDHARTA experiment we studied the X-ray transitions of 4
light kaonic atoms (H, D, 3He and 4He) using the DAFNE electron-positron collider at LNF (Italy).
The currently most precise values of the shift and width of the kaonic hydrogen 1s state were deter-
mined, which are now being used as fundamental information for the low-energy K−pinteraction
in theoretical studies. The yields of kaonic hydrogen K-series transitions and of the kaonic 3He and
4He L-series were measured, the upper limit of the X-ray yields of kaonic deuterium was determined,
important for future K−dexperiments. The shifts and widths of the kaonic 3He and 4He 2pstates
were analyzed, settling open points in this issue. In the contribution, the experimental approach
and the results of SIDDHARTA will be presented, along with plans for new experiments on kaonic
deuterium.

Spectrum of non-strange-baryons resonances by using a new mass formula
under the octic potential
Nasrin Salehi (Shahrood Branch, Islamic Azad University)
In this paper we study the spin and flavor dependent SU (6) violations in the nonstrange baryons
spectrum using a simple approach based on the new mass formula. The energy eigenvalue of each
baryon is obtained using the anzast method with the octic potential. The results of our model (the
combination of our proposed solution method, hypercentralpotentialand generalized G¨ursey Radicati
mass formula to description of the spectrum) show that the nonstrange baryons spectrum are in
general fairly well reproduced. The overall good description of the spectrum which we obtain shows
that our model can also be used to give a fair description of the energies of the excited multiplets at
least up to 3 GeV and negative-parity resonance. Moreover, we have shown our model reproduces
the position of the Roper resonances of the nucleon.

The BESIII Experiment at the Beijing Electron Positron Collider (BEPC2) has accumulated the
world’s largest samples of e+e−collisions in the tau-charm region. From these samples - which
include J/ψ,ψ(2S), and ψ(3770) decays, among others - BESIII has produced many new results in
the spectroscopy, transitions, and decays of charmonium. This talk will review the current status of
these analyses, which cover a wide range of topics from rare decays to radiative transitions to new
precision measurements.
Radiative transition studies with BESIII
Zahra Haddadi (KVI-CART), BESIII Collaboration
Charmonium spectroscopy is an ideal tool to systematically study the strong interaction between the
fundamental building blocks of matter, quarks and gluons. From a theoretical and experimental point
of view, charmonium is considered as one of the most controllable two-quark systems. Hence, pre-
cision measurements of the properties of charmonia allow a thorough study of the non-perturbative
features of the strong interaction, such as confinement and the dynamic generation of the mass
of hadrons. Radiative transitions between charmonium states can be exploited to studytheir struc-
ture and to probe states that are non-vector like. Moreover, radiative transition rates are perfect
benchmarks to test the validity of potential models and calculations that are (partially) based on
first principles, such as effect-field theoretical approaches and Lattice QCD. Over the past few years,
BESIII at the BEPCII storage ring in Beijing, China, has harvest a wealth of data on E1 and M1
radiative transitions in e+e−annihilations. These data have been used to shed light on various puz-
zles related to charmonium spectroscopy. In this presentation, we give a review on the most recent
results of BESIII related to radiative transitions.
Opportunities in open charm physics with PANDA
Andreas Herten (Forschungszentrum J¨ulich), Elisabetta Prencipe, Lu Cao, PANDA Collabora-
tion
Open-charm physics is of high interest for the study of weak and strong interactions. Recent obser-
vations in charm spectroscopy and the discovery of a number of unpredicted states continue to keep
this field of physics exciting. The PANDA experiment at FAIR (Darmstadt) is an antiproton-proton
experiment, built to study questions of hadron and nuclear physics with interactions of antiprotons
with nucleons and nuclei. The study of the charm sector is one of the key research topics of the
experiment. With the high rate of 2×107interactions per second and the 20 times higher mass
resolution than attained at B-factories, PANDA is in a privileged position to perform width mea-
surements of narrow Dsstates (Ds(2317) and Ds(2460)) and study form factors of semileptonic Ds
decays. Original contributions are also planned for the determination of cross sections of pbarp to
open-charm mesons, e.g. D+D−, as several models predict different magnitudes. In the talk, the
status of current simulations of PANDA and an overview of several benchmark channels in the D
sector will be presented.

Short-lived positron emitters in beam-on PET imaging during proton therapy

Diblen, Phebe Heeres, Aleksandra Biegun, Fine Fiedler, Marc-Jan van Goethem, Emiel van der
Graaf, Sytze Brandenburg
Due to the large dose deposit in the Bragg peak, proton beam radiotherapy is sensitive to a variety of
possible differences between the actual and planned treatment situation. Therefore, a technique for
in-vivo dose delivery verification is needed. The only such technique in clinical use today is positron
emission tomography (PET) of the positron emitters produced in the patient during irradiation. PET
during irradiation maximizes the number of counts and minimizes biological washout. In such a sce-
nario, also short-lived positron emitters will be observed. As very little is known on the production of
such nuclides, we measured the production of short-lived positron emitters in the stopping of 55 MeV
protons in water, carbon, phosphorus and calcium targets. The most copiously produced short-lived
nuclides are: 12N on carbon, 29 P on phosphorus and 38mK on calcium. No short-lived nuclides are
produced on water. The experimental results were used to calculate the number of decays, integrated
over an irradiation, in 4 tissue materials as function of the duration of the irradiation. 12N needs
to be considered as the image blurring caused by its large positron range may noticeably degrade
image quality. In (carbon-rich) adipose tissue, 12N dominates up to an irradiation duration of 70 s.
In bone tissue, 12 N dominates over 15O during the first 8-15 s. The short-lived nuclides created on
phosphorus and calcium substantially improve the visibility of bone tissue in in-beam PET compared
to PET imaging after an irradiation.
Proton radiography as a tool to improve proton stopping powers in proton
therapy treatment

The quality of the cancer treatment with protons critically depends on accurate predictions of proton
stopping powers of traversed tissues. Today, proton treatment planning is based on stopping power
information derived from X-ray Computed Tomography (CT) images. The conversion of the CT
image to proton stopping powers has systematic uncertainties in the calculated proton range in a
patient of approximately 3-4% and even up to 10% in regions containing bone. The inaccuracies
may lead to no dose at all in parts of the tumor or a very high dose in organs at risks and other
normal tissues. A direct measurement of the proton stopping power by transmission radiography of
high-energy protons will make it possible to significantly reduce these uncertainties and thereby im-
prove the quality of dose delivery. This is expected to have a positive impact on treatment outcome.
Our studies benefit from the novel gas-filled time projection chambers based on GridPix technology,
being developed at the National Institute for Subatomic Physics (Nikhef), The Netherlands, to track
a single proton entering and exiting the phantom. A BaF2calorimeter has been used to measure
the protons residual energy. Different phantom geometries and materials have been irradiated with
a scattered proton beam of 150 MeV. The experiment was simulated using the Geant4 toolkit. First
results show a good agreement between simulated and experimental energy radiographs. The multi-
ple Coulomb scattering that affects the position resolution of the proton traversing different materials
is being analyzed. Both energy and scattering angle radiographs will be discussed.

Calculation of efficiency for a high-resolution gamma-ray spectrometer used
for environmental radioactivity measurements
Ileana Radulescu (National Institute for Physics and Nuclear Engineering Horia Hulubei - IFIN
HH), Marian Romeo Calin
An accurate procedure for obtaining full energy peak efficiency for high purity germanium detectors
using measurements for experimentally calibrated samples geometries is time consuming and often
expensive. That is why methods such as Monte Carlo simulations have been proposed and examined
by means of results intercomparison. In the case proposed, the geometries used are vials of 45 mm
height and 25 mm diameter, made of glass (density: 2.50 g cm−3) with a wall thickness of 0.5 mm,
as these are the most used geometries for regular monitoring of the environmental radioactivity, on
daily/monthly bases, in the area of the institute and nearby. Measured isotopes in environmental
samples are 241Am, 137Cs, 60 Co, 40K, progenies of 238 U and 232Th series. To determine the efficiency
of the detector for these geometries quality control sample material from IAEA was used. Six vials
have been filled to different heights with soil from one quality control sample, after it has been dried
and homogenized. These calibration samples were then measured for long time. The calibration
material was modelled as soil with density 1.6 g cm−3. Detector response was simulated using
the MCNPX code, calculating the pulse height tally, that estimates the distribution of the energy
deposition which represents an energy spectrum in a physical detector. The results showed an
agreement within 5% between simulated and measured efficiencies. The Monte Carlo method has
reliable results, can be used for large range of geometries and in a cost effective way.

Muon Tomography (MT) is a burgeoning field of applied nuclear physics research. This technique
makes use of the penetrating and Coulomb-scattering properties of cosmic-ray muons to image the
internal composition of large and/or sealed containers that cannot be interrogated via conventional
means e.g. X-rays. The Nuclear Physics group at the University of Glasgow, in collaboration with
the UK National Nuclear Laboratory and Sellafield Ltd., have developed a prototype detector system
based on scintillating-fibre and multi-anode photomultiplier technologies to assess the feasibility of
using this technique in the non-destructive assay of legacy nuclear waste containers within the UK
Nuclear Industry. Images of a small, industrial waste container will be presented from experimental
scattering data collected using this MT system. These results showcase the vast potential of this
system in characterising the high-Z(atomic number) materials encapsulated within the concrete-
filled, steel container. Small uranium and lead samples are reconstructed to sub-centimetre precision
and are clearly discriminated from the low-Zconcrete background. With a full-scale system under
construction in Glasgow to accommodate 500-litre industrial waste barrels, it is foreseen that with
continued research and development this system will be deployed within the UK Nuclear Industry in
the future and will play an important role in mitigating the risks inherent with the long-term storage
of materials of this nature.

nelius Ponta, Tiberiu Sava, Corina Anca Simion, Ioana Stanculescu
Horia Hulubei Institute of Physics and Nuclear Engineering (IFIN-HH), Bucharest-Magurele, has been
involved in activities regarding the study and preservation of national cultural heritage for decades.
Initially starting with simple individual initiatives, today, the institute has solid connections with
dozens of musea, universities, other research institutes involved in the study the preservation of na-
tional cultural heritage. Very diverse in types, methods and instrumentation, our activities may be
classified mainly in: analyses using various techniques, especially nuclear and atomic ones, gamma
irradiation treatments and radiocarbon dating, plus different combinations of the above. Two tande-
tron accelerators of 3 and 1 MV and an industrial type gamma-irradiator are the largest installations
used. Through the collaborations that we have, our researchers may expand the institute‘s activities
also to using equipment from abroad. On a national level, IFIN-HH is also the promoter of modern
methods of physics and chemistry concerning cultural heritage, as well as a renowned international
leader in such activities. I will review the methods used, the installations and show a few examples
from our latest activities in the area.

The electric conductivity of the aluminium alloy SAV-1 irradiated with fast neutrons was investigated
in the fluences range 1016 −1019 n·cm−2and a temperature range 290-480 K. It is revealed on the
basis of the X-ray structure analysis that the average static displacement of atoms in the alloy in
order of magnitude comparable to their dynamic thermal displacements. It is shown that the observed
nonlinear dependence of the resistivity of the alloy on the dose and temperature due to changes in the
degree of long-range order of the crystal lattice by neutron irradiation. The mechanisms of radiation
modification of the structure of the alloy SAV-1 are discussed.

Experiment Gamma-CCB at Cyclotron Centre Bronowice focuses on investigation of gamma emission
in experimental modelling of hadron therapy, searching for manifestation of the Bragg peak in gamma
spectra. Experimental program comprises a series of measurements for different energies of the
proton beam, as well as for several phantom materials. The talk reports on the results of the
measurements performed so far, at 70 MeV proton beam energy and for two target materials: graphite
and methacrylate PMMA. Two different experimental techniques were tested, resulting in differential
gamma spectra or spectra integrated over whole proton penetration path in a phantom. Strong
correlation of the intensity of the carbon and oxygen excitation lines with the Bragg peak position
has been observed in both types of measurements, confirming the potential of the method in the
future application in hadron therapy.

Computational investigation of transmutation efficiency of 237 Np, 241/243Am
spallation targets irradiated by 1 GeV proton
Zohreh Gholamzadeh, S A H Feghhi, Zahra Alipoor (AEOI), Claudio Tenreiro
Hazardous TRan-Uranic elements obtained by spent nuclear fuel can be transmuted to shorter half-
life radioisotopes comparing before transmutation. Different scenarios are planned to transmute
the TRUs in critical or subcritical reactor cores. Transmutation such radiotoxic elements can be
considered via spallation process using charged-particle induced through a TRU target. In the present
work, transmutation efficiency of 237Np and 241/243Am targets via 1 GeV proton irradiation has been
studied separately. An optimized spallation target dimension has been determined to meet a keff
less than 0.98 for both modeled targets. The obtained computational data showed 0.349 kg/y
of 237Np transmutes due to fission reaction rate achieved by 10 µA current of a proposed proton
beam irradiated the optimized-dimension target. Also, 0.336 kg/y of the irradiated 241/243 Am target
transmutes to short-lived radioisotopes. The neptunium target experiences higher axial and radial
deposited heat than the modeled americium target.

Ion implantation is a powerful tool for the modification of polymers. The studied materials con-
tain a mixture of diglycidylether of bisphenol A (DGEBA) and monoglycidylether terminated poly
(dimethylsiloxane) (GE-PDMS) or diglycidylether terminated poly(dimethylsiloxane) (DG-PDMS) in
98/2 wt.% reinforced with 10 wt.% POSS-octa(3 glycidyloxypropyl)dimethylsiloxy) (OEP-POSS).
The presence of Au ions in the structure of these materials can have drastic effects on the electrical,
mechanical and chemical properties. In this study we present the modification of mechanical prop-
erties after 1.6 MeV Au+implantation of nanocomposites at a dose of 5.5imes1015 ions/cm2. The
polymers were examined by different methods: Thermogravimetric analysis (TGA), Dynamic mechan-
ical analysis (DMA), Rutherford Backscattering Spectrometry (RBS) and Atomic Force Microscopy
(AFM). Nanoindentation and AFM gave information regarding the hardness and topography while
RBS gave information regarding the Au presence in the samples. The work of Nicoleta Mihaela Florea
has been funded by the Sectoral Operational Programme Human Resources Development 2007-2013
of the Ministry of European Funds through the Financial Agreement POSDRU/159/1.5/S/132397.
Utilization of 241Am-9Be neutron source in PGNAA setup used in cement raw
material analysis
Hamed Panjeh (FUM Radiation Detection and Measurement Lab, Faculty of Science, Ferdowsi
University of Mashhad, Mashhad, Iran), Reza Izadi, John Kettler, Motahhareh Abbasi
Hundreds of cement factories use online bulk material analyzers to improve their quality control for
both raw material and kiln feed, and reduce their variability. The most used technology for online
analysis is Prompt Gamma Neutron Activation Analysis (PGNAA), with 252Cf as the neutron source.
Cost and short half-life of the 252Cf neutron sources are the main problems in cement industry.
Therefore, simulation and experimental study has been done to develop the setup geometry and
investigate the feasibility of using 241Am-9Be neutron source as an alternative option. Utilizing
241Am-9Be neutron source resolves the need of system periodic calibration and concern about the
cost of 252Cf neutron source renewing.

Production, purification, and analysis of a 163 Ho sample for the neutrino mass
determination

taldo
The ECHo collaboration investigates the electron capture decay (EC) of 163Ho for determining the
mass of the electron neutrino. The spectrum of the EC is recorded by metallic magnetic calorimeters
(MMC) and the neutrino mass is deduced from the analysis of the endpoint region of the spectrum.
The required 163Ho samples are produced by reactor activation of enriched 162Er. By ion exchange
chromatography a pure Ho fraction can be obtained, leaving 166mHo as the only remaining long-
lived contamination. Resonance ionization at the RISIKO mass separator offers a suitable method to
further purify the sample and to implant 163Ho into the calorimeters in a single step. This method
results in no radioactive co-implants beyond a fraction of 1 ppb with respect to 163 Ho. In addition
to the calorimetric spectrum, an independent measurement of the EC Q-value by high-precision
Penning-trap mass spectrometry is necessary to quantify systematics such as solid state effects. Ion
production from samples with only 1016 atoms was studied at TRIGA TRAP using an improved
laser ablation ion source. Determination of the Q-value was demonstrated and the uncertainty of
the atomic masses of 163Ho and 163 Dy improved by a factor of two compared to literature. This
know-how can now be used at SHIPTRAP to perform the measurements on a 50 eV uncertainty
level, thus providing the very important input for the ECHo project.
Neutrinoless double beta decay nuclear matrix elements with energy density
functional methods
Tom´as R. Rodr´ıguez (Universidad Aut´onoma de Madrid)
Potential detection of non-conserving lepton number processes, such as the neutrinoless double beta
decay, constitutes one of the most promising signals of new physics beyond the Standard Model, apart
from experiments using high energy collisions performed at LHC (CERN). In the neutrinoless double
beta decay (0νββ)two neutrons are transformed into two protons and only two electrons are emitted
in the final state. This is a very encouraging case due to its implications in fundamental physics
since it can only occur if neutrinos are massive and Majorana particles (neutrinos and antineutrinos
are identical particles). Additionally, the inverse of the half-life of this process is proportional to
the neutrino effective mass. Therefore, an eventual detection of this decay mode would determine
the absolute scale of the mass of these elementary particles. Nevertheless, there exist two main
unsolved problems in this field: 1) Despite the increasing experimental efforts, 0νββ-decay has not
been detected yet due to the very long half-lives (>1025 years) that require ultra- low background
experiments; 2) Once the half-life of a given double-beta emitter is experimentally measured, the
absolute scale of the neutrino mass can be only determined if the so-called nuclear matrix element
(NME), that connects initial and final nuclear states, is accurately known. In this contribution I will
present the current status and future perspectives for nuclear matrix elements calculations performed
with energy density functional methods.

Searching for the neutrinoless double beta decay with GERDA
Riccardo Brugnera (Universita’ di Padova and INFN Padova)
Neutrinoless double beta decay is a lepton-number violating process predicted by many extensions of
the SM. It could be the key to understand the nature of the neutrino: it would prove its Majorana
nature and the half-life of the decay would be a measure of the neutrino-mass absolute scale. The
GERmanium Detector Array (GERDA) experiment at the INFN, Gran Sasso Laboratory, Italy, is
searching for the double-beta-decay of the isotope 76Ge. Germanium crystals enriched in 76 Ge are the
source and the detector simultaneously. They are deployed into liquid argon. Data from the first phase
of GERDA (Phase I) gave no indication of neutrinoless double beta decay of 76Ge, thus disfavoring
the long-standing observation claim based on the same isotope in a model-independent way. The
measured half-life lower limit for neutrinoless double beta decay of 76Ge is T1/2>2.1×1025 (90%
C.L.); the background level achieved was a factor 10 smaller with respect to previous experiments.
The second Phase of the experiment is presently being prepared, aiming to an increase of the
sensitivity on the half-life by a factor 10: this will be achieved by collecting a larger exposure and
by further suppressing the background through the use of newly developed BEGe-type detectors and
the detection of scintillation light from the liquid argon. This presentation will summarize the basic
concept of the GERDA design; the physics results from Phase I; the status and perspectives from
Phase II.
Results from CUORE-0 experiment, status of CUORE detector, and future
perspectives for neutrinoless double beta decay at LNGS
Carmine Elvezio Pagliarone (LNGS - UNICLAM)
This talk discusses a rare nuclear transition, known as neutrinoless double beta decay (0νββ), which
is important for the exploration of the inverted hierarchy region of the neutrino mass pattern. The
Cryogenic Underground Observatory for Rare Events (CUORE) is an experiment that aims to search
for such a transition in 130Te together with other rare processes. CUORE is a cryogenic detector,
composed by an array of 988 Tellurium dioxide bolometer crystals, with a total mass of 741 kg.
CUORE is presently under construction at Laboratori Nazionali del Gran Sasso (Italy), at a depth
of about 3500 m.w.e. In order to test and demonstrate the performances of the upcoming CUORE
experiment a lower scale experiment, consisting of 52 TeO2bolometers, 750 g each, arranged in 13
layers, constructed strictly following CUORE protocols have been built. Such an experiment, called
CUORE-0, is collecting data from spring 2013. This talk presents the latest results on 0νββ coming
from CUORE-0 experiment. These results show how the good performances, in terms of background
and energy resolution, support the achievement of the CUORE target sensitivity. This talk will then
summarize the status of CUORE Experiment and the R and D activities on bolometers, currently
underway, for next-generation double-beta decay experiments.

Nuclear structure corrections for superallowed 0+→0+beta decay revisited
Latsamy Xayavong (CENBG), Nadya Smirnova
Superallowed Fermi beta decay provides one of the most important tests of the fundamental sym-
metries underlying the Standard Model of electroweak interactions. The constancy of the absolute
Ft value would confirm the conserved vector current hypothesis and allow to extract the vector cou-
pling constant and Vud matrix element of the Cabibbo-Kobayashi-Maskawa matrix with the highest
precision. At present, ft-values for fourteen 0+beta transitions are known with a precision better
than 0.1%. To extract the absolute Ft value of the data, a few radiative and a nuclear structure
corrections should be applied. The latter, which is due to the isospin-symmetry breaking in nuclear
states, still represents a great challenge for a theoretical model [1]. We present a new shell-model
calculation of a correction to superallowed Fermi beta decay for sd-shell emitters. In this study,
many-body states are constructed from modern sd-shell Hamiltonians. We focus on a radial overlap
correction, accounting for the difference between proton and neutron radial wave functions due to
the presence of the Coulomb and isovector terms in a nuclear mean-field potential. We use a phe-
nomenological Woods-Saxon potential and a self-consistent Hartree-Fock with zero-range Skyrme
forces, with various recently developed parameterizations, slightly adjusted on nucleon separation
energy and charge radii. The results are compared with previous calculations ([1] and refs. therein).
In our opinion, there is still some freedom in the selection of the WS parametrization and details of
separation energy fits.

Precise measurements of half-lives and γ-ray branching ratios of two mirror
beta decays, 23Mg and 27 Si, in order to study the weak interaction and test
the standard model
Cecile Magron (CENBG), Bertram Blank, Mathias Gerbaux, Jerome Giovinazzo, Teresa Kur-
tukian-Nieto
Beta decays are a fantastic tool to study the weak interaction described by the standard model, thus
this model can be tested by precise measurements with nuclear beta decays. Among these tests,
the conserved vector current (CVC) hypothesis and the unitarity of the Cabibbo-Kobayashi-Maskawa
(CKM) quark-mixing matrix are of great interest. The CVC hypothesis assumes that the vector
coupling constant, Gv, is a universal constant. Regarding the unitarity requirement of the CKM
matrix, the quadratic sum of the elements of the top row should add up to unity: Pi=d,s,b V2
ui = 1.
In this equation, Vud is the main term, Vud = (Gv/Gµ). To test these two properties, superallowed
Fermi beta decays have yielded the highest precision [1]. However, there are three other possibilities
to make these tests: neutron decay, pion decay and mirror beta decays. This last possibility has not
been used for long because of the difficulty of determining corrected ft values, t, and Gamow-Teller
to Fermi mixing ratios [2]. Despite these difficulties, I will focus on an accurate determination of
half-lives and γ-ray branching ratios for two mirror decays, 23 Mg and 27Si. For that, measurements
have been made at the IGISOL facility at the University of Jyvaskyla. Preliminary results will be
presented and put into the international context of weak-interaction studies.

Symmetry violations in neutron and nuclear beta decay
Keri Vos (VSI - RUG), Rob Timmermans, Hans Wilschut
Nuclear and neutron beta decay played a major role in uncovering the structure of the weak in-
teraction, but also remains important today in searches for physics beyond the Standard Model.
These searches for non-SM physics, such as novel scalar and tensor interactions, are, however, not
independent from searches in other fields, such as searches at the LHC or searches for electric dipole
moments. In this talk I will discuss the significance of beta decay in the era of LHC and I will present
a road map for future experiments.

Gerco Onderwater, Coen Pijpker, Rob Timmermans, Keri Vos
Lorentz invariance is the invariance of physical laws under boosts and rotations. It is a key assump-
tion in Special Relativity and the Standard Model of Particle Physics but has not been investigated
in detail in the weak interactions. At the Van Swinderen Institute in Groningen a theoretical and ex-
perimental research program was started to study Lorentz invariance violation (LIV). The theoretical
work led to a framework allowing a systematic approach to search for LIV in weak decays. Based
on various experiments limits were set on parameters that quantify LIV. A novel beta decay exper-
iment was designed which tests rotational invariance. Specifically, the dependence of the lifetime
of polarized 20Na atoms on the polarization direction was measured as a function of sidereal time.
The experiment sets a limit 2×10−4at 90% C.L. on sidereal variations of the relative lifetime. The
experimental method and results will be discussed within the context of the theoretical framework.

Recent results from the NA61/SHINE experiment
Andrzej Wilczek (University of Silesia)
The problem of pinning down the critical point of strongly interacting matter still puzzles the commu-
nity. One of the answers suspected to emerge in the near future will surely come from NA61/SHINE
-a fixed-target experiment aiming to discover the critical point as well as to study the properties of
the onset of deconfinement. This goal will be reached by obtaining precise data on hadron produc-
tion in proton-proton, proton-nucleus and nucleus-nucleus interactions in a wide range of system size
and collision energy. In this contribution, recent inclusive spectra and new results on fluctuations of
identified hadrons in p+pand Be+Be interactions at the SPS energies will be shown. The results
will be compared with the world data, in particular with the corresponding results of NA49 for central
Pb+Pb collisions as well as with some model predictions.
Softening of the kaon spectra in 1.9A GeV nucleus-nucleus collisions by φ(1020)
production and decay
Krzysztof Piasecki (Institute of Experimental Physics, Faculty of Physics, University of War-
saw), FOPI Collaboration
φ(1020) mesons emitted from Ni+Ni and Al+Al collisions at the beam kinetic energy of 1.9A GeV
were investigated by the FOPI Collaboration [1,2]. Significantly larger data sample was obtained
compared to our previous measurements [3]. Basic parameters of φ(1020) emission were obtained
from kinetic energy distribution. Our results are close to that obtained by the HADES Collaboration
at similar beam energy [4]. As a result of the dominant φmeson decay to K+K−pair [5], the kine-
matic spectra of K−receive a considerable feeding. We show that this contribution clearly softens
the K−spectra. In consequence, a considerable part of the gap between the inverse slopes of K−
and K+, that was observed for most of the colliding systems at similar beam energies [6], can be
explained by the influence of φmesons to the K−spectra. (K. Piasecki for the FOPI Collaboration)

QCD chiral phase transition from a (axial) vector meson extended PQM model
Peter Kovacs (Wigner Research Centre for Physics, Hungary), Gyorgy Wolf, Zsolt Szep
Chiral phase transition is investigated in the SU (3)LxSU(3)Rsymmetric (axial)vector meson
extended Polyakov Quark Meson model, which includes beside the usual scalar and pseudoscalar
nonets, the vector and axial vector nonets, constituent quarks and Polyakov loop variables. For the
determination of the model parameters at zero temperature we apply a hybrid approach, in which
mesons treated at tree-level, while the constituent quarks at 1-loop level. At finite temperature
and/or densities, the temperature and baryochemical potential dependence of the order parameters
(two scalar condensates and two Polyakov loop variables) are calculated from the hybrid 1-loop level
field equations resulting from the first derivatives of the grand canonical potential. The order of
the phase transition along the T= 0 and µB= 0 axes are determined for various parameterization
scenarios. We find that in order to have a pseudo critical temperature at µB= 0, which is consistent
with lattice results and a first order phase transition at T= 0 as a function of µBa light isoscalar
particle is needed. We investigate the behavior of different thermodynamical quantities like pressure,
entropy or energy density. The T/µBdependence of the scalar meson curvature masses are also
determined. Here we take into account the exact fermion contribution to the meson masses.

Open heavy-flavour measurements in Pb-Pb collisions with ALICE at the LHC
Sedat Altinpinar (University of Bergen), ALICE Collaboration
The Quark Gluon Plasma (QGP) is a state of matter, which is thought to have been present before
the hadron epoch in the early universe. This regime of strongly-interacting matter where quarks are
deconfined can be recreated at the Large Hadron Collider (LHC) in heavy-ion collisions. Among the
LHC experiments, ALICE is especially designed for the study of the signatures of the QGP. Heavy-
flavour hadrons are powerful probes since heavy quarks (charm and beauty) are predominantly created
in the early stage of the collision and carry along rich information by their interaction with the medium.
The mentioned interaction can be characterised by observables like the nuclear modification factor,
which is the ratio of the yield in nucleus-nucleus collisions and the cross section in pp collisions scaled
with the average nuclear overlap function. Measurements of azimuthal anisotropy can provide, in
addition to information about partonic energy loss, insight into the possible participation of heavy
quarks in the collective motion of the medium. The measurements are performed at mid-rapidity
using hadronic and semi-electronic decays, and at forward rapidity using semi-muonic decays. In
this presentation results from measurements of open heavy-flavour production in Pb-Pb collisions at
p(s)NN = 2.76 TeV in comparison with model calculations will be shown. (Sedat Altnpnar for the
ALICE Collaboration)
Open heavy-flavour production as a function of multiplicity in pp and p-Pb
collisions
Riccardo Russo (University of Turin)
The measurement of charm and beauty production cross sections in pp collisions provides a reference
for heavy-ion studies and a test for perturbative QCD calculations. In p-Pb collisions, open heavy-
flavour measurements allow one to assess the effects due to the presence of a nucleus in the initial
state, and to investigate the possible presence of final-state effects, such as jet quenching and radial
flow. Open heavy-flavour measurements as a function of the multiplicity of charged particles produced
in the collision are sensitive to the interplay between hard and soft contributions governing particle
production in hadronic collisions and could give insight into the role of multi-parton interactions
(MPI), i.e. several hard partonic interactions occuring in a single collision. We present results of
open heavy-flavour production measurements in pp and p-Pb collisions with ALICE. These results
include the production cross sections of Dmesons, reconstructed via hadronic decay channels at
mid-rapidity, and of leptons from heavy-flavour hadron decays, namely electrons measured at mid-
rapidity and muons at forward rapidity. We will show the measurement of D-meson production
as a function of charged-particle multiplicity, comparing the evolution of the per-event yield of D
mesons in different multiplicity intervals in the two collision systems. For p-Pb collisions, we present
in different multiplicity ranges the Dmeson nuclear modification factor, defined as the ratio of the
D-meson yield in p-Pb and pp collisions divided by the average number of binary nucleon-nucleon
collisions.

Jets evolution in Au+Au nuclear collisions at CBM energies
Danut Argintaru (Constanta Maritime University), Valerica Baban, Tiberiu Esanu, Madalin
Cherciu, Valeriu Grossu, Calin Besliu, Alexandru Jipa
The CBM experiment aims the study of the QCD phase diagram at low temperatures and high
baryonic densities, mainly to study the phase transition between hadrons and partons under these
conditions. There are many signals to detect the phase transition point: fluctuations, hydrodynamics,
etc. In previous studies we found as an interesting tool for analyzing of relativistic nuclear collisions:
the nuclear matter jets. Having a nonpartonic origin, the number of jets indicates the centrality of the
collision, i.e. the amount of incident energy pumped into the system, and the jet properties allowed
us to make assumptions about their origin. A liquid-gas nuclear phase transition was indicated
by the disappearance of jets. The cumulative number is another useful variable for detecting phase
transitions. Cumulative number, like jets, can be associated with density and temperature fluctuations
into the fireball initiated by a nucleus-nucleus collision. At CBM energies we expect a similar behavior
for nuclear matter and partonic jets. For this we made jet and cumulative number studies using
UrQMD and AMPT simulations (performed at the computing system YaPT from Nuclear Matter in
Extreme Conditions Research Center Faculty of Physics, Bucharest University) for Au+Au collisions
at 10, 20 and 30 GeV/nucleon. Our purpose is to study the evolution of properties of nuclear matter
jets and of cumulative number with projectile energy and with the collision centrality for testing the
sensitivity of these variables to the Equation-of-State of nuclear matter at CBM energies.
Flow analysis in CBM experiment at FAIR
Valerica Baban (Constanta Maritime University/Bucharest University), Alexandru Jipa, Danut
Argintaru
The CBM experiment aims to study heavy ion collisions at incident beam energies between 10
and 45 AGeV corresponding to high net-baryon densities and moderate temperatures of the phase
diagram of nuclear matter. Anisotropic flow defined as a correlation between the azimuthal angle of
an outgoing particle and the azimuthal angle of the impact parameter offers the access to equation
of state of strongly interacting matter. At RICH energies the studies shows that flow is developed at
very early stages of collisions at partonic level. Similar behaviors are expected at CBM energies. On
the other hand there is a lack of experimental observations in the range of energies covered by CBM.
In this work we present by comparison the possibility of applying different methods for analyzing
the flow in CBM experiment, respectively event plan method, cumulant method, Lee-Yang Zero
method. Our analysis is focused mainly on directed and elliptic flow using simulation code YaPT.
We will discuss the results compared to experimental data, AGS, STAR, close to CBM energies range.
EoS of asymmetric nuclear matter in heavy-ion collisions: dynamics and cor-
relation probes
Giuseppe Verde (IPN Orsay)
Heavy-ion collisions at intermediate energies offer the unique opportunity to study the properties of
nuclear matter and its EoS under extreme conditions of isospin asymmetry, density and temperature.
In this respect recent advances in this field have allowed to explore the constrains needed to model
the density dependence of the symmetry energy, relevant to understanding both nuclear interaction
and properties of neutron stars and supernovae explosions. Such studies require the availability of
detector facilities capable or reconstructing the collision event with high energy, angular and isotopic
resolution over a wide dynamic range. The talk will address these topics and their challenging future
perspectives within the context of the nuclear dynamics program of the FAZIA collaboration with
both stable and exotic beams. These investigations are planned to explore isospin diffusion and drift
as well as other symmetry energy probes with experiments at the INFN-LNS (Italy) and at the GANIL
laboratory (France) coupled to the INDRA 4pi detector. Particular attention will be devoted to the
role played by clustering in nuclear matter, particle-particle correlation techniques and invariant-mass
spectroscopy as fetmoscopic probes of nuclei and matter under extreme conditions. The status of
the FAZIA project and its first results from heavy-ion collision experiments will also be presented.

It is in the nature of astrophysics that many of the processes and objects one tries to understand are
physically inaccessible. Thus, it is important that those aspects that can be studied in the labora-
tory be rather well understood. One such aspect are the nuclear fusion reactions, which are at the
heart of nuclear astrophysics: they influence sensitively the nucleosynthesis of the elements in the
earliest stages of the universe and in all the objects formed thereafter, and control the associated
energy generation, neutrino luminosity, and evolution of stars. LUNA (Laboratory for Underground
Nuclear Astrophysics) is an experimental approach for the study of nuclear fusion reactions based
on an underground accelerator laboratory. Since 20 years the LUNA Collaboration has been directly
measuring cross sections of nuclear processes relevant in several astrophysical scenarios in the under-
ground laboratories of Laboratori Nazionali del Gran Sasso (LNGS) with unprecedented sensitivity.
The latest LUNA results will be presented. Future researches will be carried out in the frame of
the LUNA-MV project which aims at measuring several astrophysical key reactions. The scientific
program of LUNA-MV as well as status and schedule will be presented.
Gamma background studies in 45 m and 150 m deep mines
Tam´as Sz¨ucs (Helmholtz-Zentrum Dresden-Rossendorf)
A very low background level is a key requirement for low-energy nuclear astrophysics experiments.
A detailed high energy (Eγ>3MeV) gamma-background study with two escape-suppressed HPGe
detectors has been performed at a medium deep underground site, in the Reiche Zeche mine (150 m)
in Freiberg, Germany [1]. The new data complement a data set with the same detector at the Earth’s
surface, shallow underground (45 m) in the Felsenkeller laboratory in Dresden, Germany [2], and deep
underground (1400 m) in LNGS in Gran Sasso, Italy [3]. The detailed background data from one and
the same escape-suppressed HPGe detector at different underground depths allows the investigation of
the effect of the active and passive shielding on the high energy (Eγ>3MeV) laboratory background.
A detailed interpretation of the behaviour of different background components as a function of the
underground depth will be presented. The data show that already a shallow underground site has
sufficiently low gamma-background for many nuclear astrophysics studies when an additional active
shield is used to veto the remaining muon flux. Benefiting from these low background conditions, a
used 5MV Pelletron tandem accelerator is currently being refurbished for installation at the Dresden
Felsenkeller [4].

Status of the direct search for the Ec.m. = 138 keV resonance in 23Na(p, γ)24 Mg
at LUNA
Axel Boeltzig (Gran Sasso Science Institute), Andreas Best, Gianluca Imbriani, Matthias Junker
Asymptotic Giant Branch (AGB) stars play a fundamental role in the determination of the observed
abundances of light mass elements. Despite great efforts, model predictions for AGB yields are rather
uncertain due to the complex physical structure and the weakly constrained mass-loss rates and
convection efficiencies. In addition, the poor knowledge of the cross sections of the relevant proton
capture reactions diminishes the reliability of the model predictions particularly for light element
yields. The reaction 23Na(p, γ )24Mg links the NeNa and the MgAl cycles of stellar burning, hence
the precise knowledge of its cross section is crucial. For a resonance of this reaction at 138 keV only an
upper limit of 5.17 neV (95% confidence limit) could be established for its strength, with indications
of a signal at (2.15 ±1.29) neV (68% confidence level) [1]. Measurements at LUNA, the Laboratory
Underground for Nuclear Astrophysics, are aimed at a direct observation of this resonance with a
segmented bismuth germanium oxide (BGO) detector [2] to determine the resonance strength more
precisely or to provide an improved upper limit. Compared to previous experimental efforts, LUNA
benefits from an increased sensitivity thanks to reduced backgrounds due to its location underground
at the Gran Sasso National Laboratories (LNGS) and a massive shielding. The current status of the
experimental efforts will be presented, covering the setup and the preliminary results of studies and
measurements.

Muon capture on the deuteron: the MuSun experiment
Frederik Wauters (University of Washington), Peter Kammel, David Hertzog, Rachel Ryan,
Michael Murray, Duncan Prindle
QCD-based effective field theories are becoming increasingly more powerful in describing few-body
nuclear systems. These models establish a quantitative relationship between muon capture rates
and fundamental astrophysical processes from which cross sections can not be measured in the
laboratory, such as pp fusion in our sun. The MuSun experiment is measuring the muon capture rate
on the deuteron via a precise measurement of the lifetime of negative muons in deuterium. Such
a measurement unambiguously determines the low energy constant related to the strengths of the
axial coupling to the two nucleon-system. Located at the Paul Scherrer Institute, data-taking started
in 2011, and a final production run is planned for this summer. In this talk, I will present the status
of the experimental program and the progress of the data analysis towards a first physics result. In
particular, I will discuss how we deal with the systematics related with the event selection in our
active-target time projection chamber (TPC). This cryogenic TPC, filled with ultra-pure deuterium,
enables us to unambiguously measure the capture rate of negative muons from the doublet state of
a muonic deuteron atom.

Experimental study of the 13C+12 C fusion reaction at deep sub-barrier ener-
gies
Mihai Straticiuc (IFIN-HH), L Trache, X. Tang, Y.J. Li, D Chesneanu, S Toma, Dan Gabriel
Ghita, Ion Burducea, R. Margineanu, Ana Pantelica, C. Gomoiu, N.T. Zhang
Heavy-ion fusion reactions between light nuclei such as carbon and oxygen isotopes have been studied
because of their significance for a wide variety of stellar burning scenarios. One important stellar
reaction is 12C+12 C, but it is difficult to measure it in the Gamow window because of very low cross
sections and several resonances occurring. Hints can be obtained from the study of 13C+12 C reaction.
We have measured it by an activation method for energies down to Ecm = 2.5MeV using 13C beams
from the Bucharest 3 MV tandetron and gamma-ray deactivation measurements from the resulting
24Na, in our low and ultra-low background laboratories. The latter is located in a salt mine about
100 km north of Bucharest. Results of the experiments so far are shown and discussed in connection
with the possibility to go even further down in energy and with the interpretation of the reaction
mechanism at such deep sub-barrier energies. Possibilities to further use the combination high current
tandetron accelerator and ultra-low background salt mine laboratory for nuclear astrophysics are also
assessed.
Reason for the existence of 56Fe than 62Ni in supernovae remnants
S. Santhosh Kumar (Department of Physics, Bharathidasan Govt. Coll. for Women, Puducher-
ry, India), P. Preetha
In astrophysics, the rates of neutron-capture reactions in r and s processes are proportional to the
nuclear level densities (NLD) and are important in the synthesis of elements heavier than iron. The
most abundant isotope of iron, 56 Fe, originates from an unstable isotope of nickel, 56Ni. This isotope
is produced in supernovae and decays first to Cobalt and then to iron. Still the question of existence
of 56Fe than 62Ni in supernovae is unanswered, even though the mean binding energy difference is
of no importance to the theory of supernovae. Truran et al., favoured 56Fe has the highest BE/A,
but Clifford and Taylor are the first to identify 62Ni has the highest mean binding energy. In this
work we tried to answer the reason for the existence of 56Fe than 62Ni in supernovae remnants in
the context of excitation energy, level density and thermal fluctuation, etc. The binding energy per
nucleon in the mass region A= 50 −64 using Droplet model mass formula is calculated and found
the nuclei 58Fe(8.76681 MeV) and 62Ni(8.76789 MeV) are strongly bound than 56 Fe(8.74831 MeV),
which is in correlation with Fewell. The level density parameter (ldp) is determined, under statistical
assumptions, by the relation between excitation energy and entropy. Nuclear structure effects upon
the ldp can be considered by the inclusion of shell corrections, pairing correlations and collective
excitations. The interrelation between structure and rotational effects in the stability of 56Fe is also
discussed.

In-beam and activation experiments for γ-process nucleosynthesis at the Uni-
versity of Cologne
Lars Netterdon (Institute for Nuclear Physics, University of Cologne), Jan Mayer, Philipp
Scholz, Andreas Zilges
The majority of the neutron-deficient p-nuclei, bypassed by the sand rprocess, is believed to be
produced during the γprocess. During this process, the nuclei are synthesized by a network of
photodisintegration reactions and β-decays. Reaction rates for the γ-process network are mainly
predicted by statistical-model calculations as experimental data are scarce. To reduce the uncertain-
ties in these calculations from the nuclear physics side, input parameters entering these calculations
such as optical-model potentials and the γ-ray strength function must be constrained experimen-
tally. In this talk, an overview of experiments aiming at these input parameters using complementary
approaches will be given. A setup for in-beam experiments with high-purity germanium detectors
utilizing the γ-ray detector array HORUS at the Institute for Nuclear Physics in Cologne will be
presented. Total and partial cross sections of the proton-capture reaction 89Y(p, γ)90 Zr will be
discussed, allowing constraints on the γ-ray strength function in 90Zr [1]. The 112Sn(α, γ )116Te re-
action will be presented, being the first successful in-beam α-capture experiment on a heavy nucleus
to date [2]. Moreover, activation experiments using the Cologne Clover Counting setup to refine
α+nucleus optical model potentials will be presented. The reactions 187 Re(α, n)and 108Cd(α, n)
will be exemplarily discussed. Supported by the ULDETIS project within the UoC Excellence Initia-
tive institutional strategy and by the Deutsche Forschungsgemeinschaft under contract DFG (INST

The impact of new thermonuclear reaction rates of 64Ge(p, γ)65As & 65As(p, γ)66 Se
for type-I X-ray bursts
Yek Wah Lam (Institute of Modern Physics, Chinese Academy of Sciences), Jian Jun He, Anuj
Parikh
We derived new thermonuclear 64Ge(p, γ)65 As and 65As(p, γ)66Se reaction rates based on recently
evaluated proton separation energies Spand nuclear structure data from large-scale shell model
calculation. These two rp processes are sensitive to adequately small change of Sp values, spectro-
scopic factors of proton captures, and densities of excited states of the final nucleus. The precisely
measured and evaluated proton separation energies, Sp(65As)and Sp(66Se), largely influence the
rates compared to currently available JINA data sets, REACLIB, particularly about two order for
64Ge(p, γ )rate. By using one-zone post-processing type I X-ray burst model simulating the nucle-
osynthesis within accreted envelopes of neutron stars in close binary systems, we found that the new
rates based on newly evaluated Sp(65As) and Sp(66 Se) values, resonant energies, and spectroscopic
factors estimated from shell model significantly affects the productions of nuclide in the range of
64 ≤A≤110 about one to ten times compared to productions of nuclide based on presently
available REACLIB data. The astrophysical impact of our new rates will be presented.

cel, Sorin Pascu, Nicolae Victor Zamfir
Preliminary alpha capture cross sections on p-nuclei at energies close to the Gamow window will
be presented. The cross section were measured by means of the activation method using an al-
pha beam delivered by the IFIN-HH tandem accelerator. The induced activities were measured in
close-to-detection geometry using two large volume HPGe detectors in a low background passive
shielding.
Investigation of the 3He(α, γ)7Be reaction using the Asymptotic Normalization
Coefficient technique
Gabor Kiss (Atomki)
The 3He(α, γ)7Be reaction plays an important role in several astrophysical scenarios including stellar
hydrogen burning and Big Bang nucleosynthesis [1]. Contrary to its importance and despite the large
number of experimental and theoretical works devoted to this reaction the knowledge on the reaction
cross section at the relevant energies is still limited and further experimental efforts are needed [2,3].
The precisely knowledge on the external capture contribution to the 3He(α, γ)7Be reaction cross
section is of crucial for the theoretical description of the reaction mechanism. Therefore, the aim of
the present work is to measure this direct contribution using the Asymptotic Normalization Coefficient
technique [4] and through this to improve our knowledge on the reaction rate at the temperatures
of the solar core. To extract the 3He(α, γ)7Be reaction cross section, the angular distribution of
deuterons emitted in the 6Li(3He,d)7Be α-transfer reaction was measured with high precision at
several energies. The experimental details and the preliminary results are planned to be presented.

A QCD ghost reconstruction scheme for f(T) gravity in flat FRW universe
Surajit Chattopadhyay (Pailan College of Management and Technology, Kolkata)
Accelerated expansion of our universe, as evidenced by Supernovae Ia (SNeIa), Cosmic Microwave
Background (CMB) radiation anisotropies, Large Scale Structure (LSS) and X-ray experiments, is
well documented in literature. A missing energy component, also known as Dark Energy (DE) with
negative pressure, is widely considered by scientists as the responsible of this accelerated expansion.
A DE model, so-called Veneziano ghost DE (GDE), has been proposed in [1]. The key ingredient of
this new model is that the Veneziano ghost, which is unphysical in the usual Minkowski spacetime
quantum field theory (QFT), exhibits important physical effects in dynamical spacetime or spacetime
with non-trivial topology. Veneziano ghost is supposed to exist for solving the U(1) problem in the
low-energy effective theory of QCD [2]. Two models of f(T) have been generated through QCD-ghost
dark energy and the pressure and density contributions due to torsion have been reconstructed. Two
realistic models have been obtained and the effective equations of state have been studied. Also, the
squared speed of sound has been studied to examine the stability of the models.

Some advances in the microscopic foundations of the Interacting Boson Model
Jose Barea (Universidad de Concepcion)
The traditional interpretation of pairs of nucleons coupled to angular momentum 0 and 2 as bosons
in the Interacting Boson Model is revisited. In contrast to previous calculations, where extensive
use of the Number Operator Approximation (N.O.A.) is made, we show new calculations of spectro-
scopic intensities of one nucleon transfer reactions and log ft values of single beta decays where this
approximation is relaxed. We compare the results obtained with and without using N.O.A. with the
experiment and the overall agreement between them is better without using N.O.A..
Dynamics of two-cluster systems in phase space
Yuliya Lashko (Bogolyubov Institute for Theoretical Physics, Kiev, Ukraine), Gennady Filippov,
Viktor Vasilevsky
We present a phase-space representation of quantum state vectors for two-cluster systems which is
valid both for finite hbar and when hbar goes to zero. The Bargmann-Segal transformation was
used to map wave functions of two-cluster systems in the coordinate space into the Fock-Bargmann
space. The density distribution in the phase space was compared with those in the coordinate and
momentum representations. Density distributions in the Fock-Bargmann space were constructed for
bound and resonance states of 6,7Li and 7,8Be, provided that all these nuclei are treated within a
microscopic two-cluster model. The microscopic model is based on the resonating-group method
and uses a full set of oscillator functions to expand a wave function of relative motion of interacting
clusters. The dominant two-cluster partition of each nucleus was taken into consideration. The
input parameters of the model and nucleon-nucleon potential were selected to optimize description
of the internal structure of clusters and to reproduce position of the ground state with respect to
the two-cluster threshold. We considered a wide range of excitation energies of compound systems,
but special attention was devoted to the bound and resonance states. Bound states and narrow
resonance states realize themselves in a very compact area of the phase space. We establish the
quantitative boundaries of this region for the nuclei under consideration. Phase portraits of the
high-energy excited states peak along the line which coincides with a classical trajectory.
Effects of 3N force and Coulomb interaction studied in deuteron breakup
reaction
Elzbieta Stephan (Institute of Physics, University of Silesia), Stanislaw Kistryn
Precise understanding of nuclear interaction is the basis for correct description of properties of nuclei
and reactions involving them. Systems of three nucleons (3N) can be treated as a testing ground
for the modern approaches to describe nuclear interaction, since for them exact theoretical calcula-
tions can be performed. At intermediate energies, observables for 3N systems are sensitive to subtle
effects of the dynamics beyond the pairwise nucleon-nucleon force, so-called 3N-force, as well as to
Coulomb interaction between protons and/or relativistic effects. Breakup of a deuteron in collision
with a proton leads to the final state of three free nucleons, with a variety of possible kinematic con-
figurations, revealing locally enhanced sensitivity to particular aspects of the dynamics. This feature
makes the breakup reaction a very versatile tool for validation of the theoretical models. Database
for the breakup reaction has recently been significantly enriched with precise differential cross section
data, vector (proton) analyzing power and vector and tensor (deuteron) analyzing powers, collected
with detection systems covering large parts of the phase space. A series of experiments performed
at KVI Groningen and FZ-J¨ulich led to several important findings concerning the role of 3N-force
and of Coulomb interaction, as well as indicating problems in description of polarization-related ob-
servables. The experimental program is continued at the new proton accelerator facility, Cyclotron
Center Bronowice in Krakow, Poland.

Experimental studies of d(1H, pp)nand d(2H, dp)nreactions at beam energy of
160 MeV
Elzbieta Stephan (Institute of Physics, University of Silesia), Izabela Ciepal, Barbara Klos, Wik-
tor Parol, Ghanshyam Khatri, Stanislaw Kistryn, Adam Kozela
A series of experiments studying a few nucleon systems in continuum of 3-body final states was
performed at KVI Groningen with the use of BINA detector. The studies were mainly devoted to
the system of three nucleons. The differential cross section data obtained for d(1H, pp)nreaction at
beam energy of 160 MeV (80 MeV/nucleon) will be presented and compared to the state-of-the-art
calculations, in particular with the aim to conclude on the role of the so-called three-nucleon force
(3NF). The 4N ensemble reveals already the complexity of heavier systems, e.g. variety of entrance
and exit channels, various total isospin states etc. This feature poses challenges, but also introduces
an enhanced sensitivity to certain aspects of the nuclear dynamics, manifested in various channels
and configurations. Expected enhancement of 3NF effects was the motivation to extend the experi-
mental studies to the 4N systems. The first results obtained d(2H, dp)nreaction at 160 MeV beam
energy will be shown. In the first place, the differential cross section for configurations ”not far”
from quasi-free deuteron-proton scattering are considered.
Two-body force in three-body system: a case of (d, p)reactions
Natalia Timofeyuk (University of Surrey)
One-neutron transfer reactions A(d, p)Bare often described by a three-body n+p+A model due to
importance of deuteron breakup. All models used to treat this breakup assume that the two-body
n−Aand p−Ainteractions are described by the corresponding local optical potentials taken at half
the deuteron energy. The present talk shows that projection of the n+p+Amany-body function
into the three-body channel leads to the p−Aand n−Ainteractions different to those used in these
models. Such interactions are given by complicated non-local energy-dependent optical operators.
However, in the particular case of (d, p)reactions, it is possible to make reasonable simplifications
of the n−Aand p−Aoptical potentials reducing them to non-local energy-dependent nucleon
optical potentials calculated at half the deuteron energy plus an expectation value of the n−p
kinetic energy over the range of the n−pinteraction. This shifts the nucleon energies used in
three-body calculations of (d, p)reactions thus affecting the theoretical (d, p)cross sections and the
spectroscopic factors extracted comparison between the theoretical and experimental cross sections
of these reactions. A few examples demonstrating this effect in A(d, p)Bwill be presented.
Calibration of backward ball scintillators of the BINA detection system
Mohammad Taqy Bayat (Payam Noor University, Tehran, Iran), Mohammad Eslami-Kalantari,
Nasser Kalantar-Nayestanaki, Johan G. Messchendorp
BINA is an experimental setup with a nearly 4πgeometrical acceptance that has been developed
in 2004 at KVI and designed for studying three- and four-nucleon scattering processes. BINA is
composed of two main parts, a forward wall and the backward ball. The forward wall consists of
two components, namely a hodoscope of segmented thin and thick scintillators and a Multi Wire
Proportional Chamber (MWPC). The scintillators are used for the particle identification and for the
energy measurement of scattered protons and deuterons (∆E−E). The MWPC is used to obtain the
scattering angles of these particles. The forward part of BINA has been designed to detect particles
at scattering angles between 10◦to 35◦. The backward ball consists of 149 fast and slow scintillators
for a ∆E−Emeasurement. The backward part covers polar angles between 35◦to 165◦with nearly
full azimuthal coverage. Our aim is to measure differential cross sections of the p-d elastic reaction
at 135 MeV and at large scattering angles., For this, we are developing a calibrating procedure for the
ball detectors of BINA based on a kinematical approach and by making use of GEANT3 simulations.
In this contribution, we will present the preliminary results of the ball calibration.

Investigation of the time-reversal invariance in pd radiative capture reaction
Ali Akbar Mehmandoost-Khajeh-Dad (University of Sistan and Baluchestan)
Experimental differential cross sections of proton deuteron radiative capture and the photo-disinte-
gration of 3He are compared at the same center of mass angle as a function of energy. The pro-
ton deuteron radiative capture (PDRC) differential cross sections are multiplied by an appropriate
detailed-balance factor. For Eγ>50 MeV the PDRC results have good agreement with the inverse
reaction results which is a test of time-reversal invariance in the electromagnetic interaction. For
30 < Eγ<50 MeV there is no agreement between the PDRC and the inverse reaction results.

Monte Carlo simulation approach for generating NaI Detector Response Func-
tions (DRFs) to account for delayed gammas due to detector activation
Hamed Panjeh, Motahhareh Abbasi (Department of Physics, Faculty of Science, Guilan Univer-
sity, Rasht, Iran), John Kettler, Reza Izadi
During neutron irradiation in Prompt Gamma Neutron Activation Analysis (PGNAA), absorption
of thermal neutrons by the detector is inevitable. Therefore, the final gamma spectrum will be a
mixture of natural background, delayed and prompt gamma-rays originated from different setup parts
including moderator, sample and detector itself. A Delayed-Gamma-Monte-Carlo Code (DGMC) was
written to determine delayed gamma neutron activation spectrum arising from an active detector.
Spectral response of 3”×3” Na(Tl) crystal to thermal neutron beam was also simulated while the
neutron beam was ”on”.
Delayed crosstalk and afterpulsing evaluation in silicon photomultipliers

Hungary), Giorgio Fallica, Jozsef Molnar, Massimo Mazzillo, Lucio Renna, Giuseppina Valvo,
Delfo Sanfilippo
Crosstalk and afterpulsing in silicon photomultipliers can strongly limit the photon-counting reso-
lution and dynamic range of the sensors. In this work we present a method and measurements to
separate the afterpulse and delayed crosstalk components of the delayed correlated pulses in the
silicon photomultiplier signal. On one hand, the motivation was to understand the relative contribu-
tions of the delayed crosstalk and afterpulses, on the other hand, to investigate the dependency of
these components on the substrate doping level. It has been found that the contribution of delayed
crosstalk pulses to the silicon photomultiplier signal can be significant (11, 5 and 3%) respect to the
contribution of the afterpulses (4.2, 1.2 and 0.8%). As well, even if one suppresses the afterpulses by
applying a longer recharge time, the delayed crosstalk component remains unaffected. A decreasing
tendency of the delayed crosstalk and afterpulsing contribution was measured with the increase of
the substrate doping. The higher the doping level, the shorter diffusion length, that is, the carriers
generated in deeper region of the substrate have a decreasing probability to reach the active region.
However, the affect of doping on the afterpulses suggests that the phenomenon of afterpulsing is not
strictly located in the microcell, but also related to the deeper region of the device.

The CsI-Silicon Particle detector for Heavy ions Orbiting in Storage rings (CsISiPHOS) was designed
and developed for β-decay studies at the Experimental Storage Ring (ESR) and as a prototype of
the in-pocket detectors for the ILIMA programme at the future Collector Ring (CR) at FAIR. The
detector serves as a ∆E/E telescope to be used for detection and identification of each incident
ion. Furthermore, from the position determined using a DSSD the trajectory of ions which have
changed their charge (by β-decay or electron capture/loss) at certain positions in the ESR can be
traced back. In a recent commissioning experiment the detector was employed to measure the β+
decay rate of H-like 142
60 Pm+ions into 142
59 Nd+. With a resolution (FWHM) of 60 MeV in the silicon
detectors at ∆E=6.7 GeV, and a total energy resolution of 330 MeV at E=56.8 GeV, the detector
can identify neighbouring isobars in this mass range distinctly. In this presentation, we report on the
design of the detector and the preliminary results from the experiment. This work was supported
by the BMBF project 05P12RGFNJ (Multi-purpose pocket detector for in-ring decay spectroscopy),

The residual nuclei yields are of great importance for the estimation of basic radiation-technology
characteristics (like a total target activity, production of long-lived nuclides etc.) of accelerator
driven systems planned for transmutation of spent nuclear fuel and for a design of radioisotopes
production facilities. Experimental data are also essential for validation of nuclear codes describing
various stages of a spallation reaction. Therefore, products of proton induced spallation reaction
of 232Th are studied by means of activation measurement and gamma spectroscopy methods. The
samples made of thin natural thorium foils were irradiated at JINR Phasotron accelerator with a
direct proton beam. Two experiments were performed with 200 MeV and 400 MeV beam energies.
Experimental cumulative and independent cross-sections were determined for more than 80 isotopes
including meta-stable isomers. Non-symmetrical mass yield fission curve was reconstructed. The re-
sults were compared with previously measured values in the case of 200 MeV experiment to validate
used data processing methodology. Cross-sections were also compared with MCNP6 Monte-Carlo
code predictions. Several different combinations of high-energy event generators and nuclear models
were used (CEM.03.03, Bertini and INCL). Generally, experimental and calculated cross-sections are
in a reasonably good agreement for both proton beam energies, with the exception of a few isotopes.
Similarly, agreement between new and previously measured data for 200 MeV is good, providing an
adequate credibility for the new 400 MeV results.

Dissipative effects in fission investigated with spallation reactions of 208 Pb
Jose Luis Rodriguez Sanchez (University of Santiago de Compostela)
In fission, the investigation of different experimental observables has shown evidences that the viscos-
ity of the medium changes with the deformation, but also with the nuclear temperature [1]. However,
these ideas are still under debate because there conclusions could be biased by the experimental con-
ditions. We propose then to investigate these effects with complete kinematic measurements of
the fission products at high excitation energy, low angular momentum and small compound nucleus
deformation, where dissipative effects should manifest in a clear way. We will report recent results
obtained at GSI for the reaction 208Pb+p at 500AMeV. This reaction fulfills the optimum conditions
for the investigation of dissipative effects in fission. Moreover, the new SOFIA setup [2] allowed us
to construct observables providing information on the fissioning nucleus, and its saddle and scission
configurations. In particular, the unambiguous identification in mass and atomic number of both
fission fragments, obtained for the first time in this experiment, was a key achievement. The fission
cross sections and the charge distribution of the fission fragments were used to study the presaddle
dynamics at small deformation [3,4]. In this work, we will present the results concerning the mass
distribution of the fission fragments, which should help us to investigate the postsaddle dynamics.

Two-body orbital electron-capture (EC) decay of stored and cooled highly charged ions has been
studied in the Experimental Storage Ring (ESR) at GSI Helmholtzzentrum in Darmstadt, Germany.
The H-like 142
60 Pm+ions were produced by fragmentation of 600 AMeV 152Sm ions in a Be-target.
The 142
60 Pm+fragments were separated in-flight by the FRagment Seperator (FRS), injected into the
ESR storage ring at 400 MeV/u and cooled to high phase-space density by stochastic and electron
cooling. More than 10 000 EC decays have been recorded in a recent experiment at October 2014
by means of a 245 MHz resonator serving as a Schottky detector. This device revealed the true
EC-decay time of single stored ions within 32 ms as identified by a tiny change of their revolution
frequency. Moreover, owing to the high sensitivity and performance of this resonator also the velocity
and momentum of the recoiling daughter nucleus immediately after the decay could be determined.
The data analysis of indepented groups is still in progress. This study presents the results obtained
from the recent experiment of orbital electron capture decay of 142
60 Pm+ions at the ESR.

ALTO a facility for stable and radioactive beam studies
Georgi Georgiev (CSNSM)
The ALTO facility in Orsay consists of two accelerators within the same installation. A Tandem
accelerator (15 MV) is dedicated to the production of stable beams (ions and cluster) for nuclear-
and atomic-physics studies. A linear electron accelerator (50 MeV) is dedicated to the production
of radioactive beams using the photo-fission on UCx targets. The provided stable and radioactive
ions beams and clusters allow covering a large physics case from nuclear structure to atomic physics,
cluster physics, biology and nano-technology. Nuclear structure studies far from stability are per-
formed at the ISOL facility. The Split-Pole and the Bacchus spectrometers are used for nuclear
reaction studies, both from astrophysical and nuclear structure interest. Gamma-ray spectroscopy
has traditionally been an important part of the scientific program with the use of different high-
efficiency spectrometers (ORGAM, MINORCA and PARIS in near future). The recent development
of LICORNE fast-neutron source has boosted the fission studies at ALTO. A brief description of the
facility will be given and the on-going research program and future developments will be presented.
High accuracy neutron inelastic cross section measurements on 206Pb
Alexandru Negret (IFIN-HH, Romania)
The design of the Generation IV lead-cooled fast reactors and of the future accelerator-driven systems
require the knowledge of neutron inelastic cross sections on 206Pb with a precision of the order of
5%. An extended experiment consisting of two largely independent measurements was conducted
at the GELINA neutron source operated by EC-JRC-IRMM. We present in detail the experimental
technique we used in order to achieve the high precision required by the applications. The results
are compared with previous experimental data and with various theoretical calculations.

CCT or no CT, that is the question
Ulli K¨oster (Institut Laue-Langevin), Patric Holmvall, Andreas Heinz, Thomas Nilsson, Aure-
lien Blanc, Herbert Faust
A new mode of nuclear fission had been reported by the FOBOS collaboration: Collinear Cluster
Tripartition (CCT). It was indirectly derived from “missing mass events” in fission studies with the
2v and v-E methods. The proposed CCT seems to be an astonishing new aspect of nuclear fission,
theoretically difficult to reconcile with traditional fission models and experimentally surprising since
the relatively high yield of such events (about 0.5% with respect to binary fission) should have shown
up in previous experiments. These claims call for an independent verification with a different exper-
imental technique. We report on direct searches for CCT events in 235U(n,f) that should manifest
in a considerable excess yield around A= 68 −70 compared to known binary fission events. The
experiments were performed with the fission fragment spectrometer LOHENGRIN at the high flux
reactor of Institut Laue-Langevin. This spectrometer provides excellent mass and energy resolution
and allows clean measurements down to relative fission yields of 10−10. In addition, the kinetic en-
ergy phase space of CCT has been derived theoretically. The known yields of far asymmetric binary
fission were confirmed but no indication for CCT events was found. Our upper limit of 1E-8 per
fission for CCT events with A=68,70 is more than five orders of magnitude below the yields claimed
by the FOBOS collaboration.
Large scale Bayesian data evaluation with consistent model defects
Georg Schnabel (TU Wien, Atominstitut), Helmut Leeb
The aim of nuclear data evaluation is to provide consistent sets of best estimates of reaction cross
sections and spectra of nuclei. These evaluated data sets are an important prerequisite for the design
of safe and efficient nuclear facilities such as nuclear power plants, fusion devices and medical devices
using radiation for diagnosis and treatment. Therefore, evaluation methods should be statistically
sound and based on physics principles in order to produce reliable results. We present a Bayesian
evaluation method to consistently estimate a huge number of observables such as cross sections,
spectra and angle-differential cross sections. The method relies on both experimental data and
model calculations to generate estimates and associated uncertainty bounds. Deficiencies of the
nuclear model are taken into account in a statistical sound way. Two novel features distinguish
this evaluation method from other approaches: First, the magnitude of the model error is explicitly
estimated; and second, the treatment of the model error is done in a way that preserves important
consistency constraints on the observables, such as sum rules of cross sections. Work partly supported
by the EC project CHANDA and the Austrian Academy of Sciences via a KKK¨
O Impulsprojekt. The
use of the Vienna Scientific Cluster for part of the calculations is acknowledged.
On the possibility to observe a proton beta decay in a colliding system
Catalin Borcea (IFIN-HH Romania)
The possibility to observe a proton beta decay in a sub-barrier Rutherford scattering of a proton on
a high Znucleus is examined. Due to the potential energy of the proton in the Coulomb field, a
strong enhancement of the phase space for beta decay takes place, creating the circumstances for
observing such events. A rough (however realistic) estimate of the rate of expected decays is also
given.

Exotic radioactivity and decays studied by tracking technique
Ivan Mukha (GSI, Darmstadt)
The isotopes within the limiting lines of bound nuclei (or drip-lines) are goals of exploration for
as many elements as possible. However the drip-line is not the end of the nuclear existence, and
nuclei beyond the proton and neutron drip-lines may live much longer than the characteristic time
of an orbital motion of nucleons in nuclei. These nuclei called resonances have lifetimes determined
by the centrifugal and Coulomb barriers and also are strongly affected by pair nucleon correlations.
Nuclear resonances can be studied by their decays via emission of proton(s) or neutron(s), or proton
or neutron radioactivity, respectively. Outside the proton drip-line, proton radioactivity prevails
and some isotopes with two-proton decays have been observed. They allow studying two-proton
correlations in nuclei. Four-proton decay is also expected in some very exotic proton-rich nuclei.
The new experimental results on two-proton decays of 19Mg and previously unobserved 30Ar, 29 Ar
isotopes will be presented. Their decays in-flight have been studied by using tracking technique which
allows for measurements of lifetime and decay energy. Also neutron radioactivity will be reviewed.
Theoretical predictions of this still unobserved phenomenon, the recent experimental activity and
plans will be presented. In particular, the case of two-neutron decay of 26O will be considered in
detail. Prospective candidates for observation of neutron radioactivity and the related experimental
methods and detectors will be discussed.
Resonance phenomena in heavy nuclei collisions and dynamical Stark effect
for nuclei in super strong laser field
Alexander Glushkov (Odessa State University-OSENU)
We present new approach for studying interaction of the finite Fermi systems (nuclei) with an super-
intense external fields (laser field). It is the combined relativistic operator perturbation theory (OPT)
and relativistic energy formalism (REA) [1]. We present new results of AC Stark shifts of single pro-
ton states in the nuclei 16O, 168 Er and compared these data with known results by Keitel et al [2].
New data are also listed for the 57Fe,171Yb nuclei. Shifts of several keV are reached at intensities
of roughly 1034 W/cm2for O and 1032 W/cm2. New unified approach (OPT+REA) [1] is used for
studying the electron-positron pair production (EPPP) in heavy nuclei collisions and treating a com-
pound nucleus in a field. Heavy ions collisions near the Coulomb barrier are surrounded by existence
of narrow e+line in a positron spectra [1,2]. The positron spectrum narrow peaks as a spectrum
of the resonance states of compound super heavy nucleus are treated. The calculation results for
cross-sections at different collision energies for 238U+238U, 232 Th+250Cf pairs are presented.

The strong force doesn’t exist
Bernard Schaeffer (Paris, France)
After one century of phenomenological formalism, the calculation of the binding energy of the sim-
plest bound nucleus, the deuteron, remains a puzzle because of misconceptions (nucleons orbiting
around nothing, charge independence, centrifugal barrier, strong force and Co, magic numbers, un-
observable observables, virtual particles). Nuclear Physics A considers that electromagnetism ”does
not match the state of the art in nuclear physics studies”, ignoring the magnetic moments of the
nucleons, discovered 70 years ago. In fact, the magnetic repulsion between nucleons is equilibrated
STATICALLY by the not so weak electric attraction induced by a proton on a not so neutral neutron.
Applying only fundamental laws and constants, WITHOUT FIT, the binding energies of nuclei have
been obtained from the STATIC equilibrium between the attractive 1/r electric Coulomb potential
and the repulsive 1/r3magnetic Poisson potential, essentially between a proton and a neutron. On
the graph below, the saddle points, unique for a given nucleus, coincide with the 2H and 4He ex-
perimental nuclear binding energies. This is not by chance, it proves the electromagnetic nature of
the nuclear energy. The great discoveries in physics are condensed into simple formulas: E=hν,
Ee ∼1/r,Em ∼1/r3,E=mc2,E=α2mc2and, now, E=αmc2for the nuclear energy, the
missing link between mass and chemical energies. The make-believe conventional nuclear theories
will disappear as geocentrism, phlogiston, caloric, aether, plum-pudding model.

Young Minds
The EPS Young Minds Project
Ulrike Ritzmann (University of Konstanz, Germany)
Boosting the creativity of students and postdoctoral researchers alike, the Young Minds Project is
an initiative of the European Physical Society to promote the next generation of leaders in physics
by creating an environment where young physicists assume an active role. After 5 years, Young
Minds counts more than 30 Sections in 19 countries. International networking, young researchers
involvement with the scientific community, promotion of science among local communities-these
should be the goals of every young researcher in Europe. Of course, these highly rewarding activities
are time consuming and the focus of most young minds is on getting their research tasks done,
being it in the lab or in front of a computer. But strong institutional support, with departments
and national societies, can be a decisive factor in encouraging young physicists to take an active
part in outreach. Through the Young Minds Project, EPS aims to encourage all active young
scientists, from undergraduates to postdoctoral researchers, to organize local Young Minds Sections
that will collaborate to develop scientific, networking and outreach activities. The YMP encourages
the interaction amongst Sections and students through various levels of international networking:
one- to-one exchanges between Young Minds Sections; European-level student conferences; and
interaction with the student groups of other organizations.

The FameLab project
Bart van der Laar (Science LinX, University of Groningen)
FameLab aims to discover charismatic, up-and-coming scientists who inspire people to see the world
from a new perspective in just three minutes! Since its birth at the Cheltenham Science Festival in
2005, FameLab has grown into arguably the worlds leading science communication competition. A
partnership with the British Council since 2007 has seen the competition go global with more than
5000 young scientists and engineers participating in over 27 different countries. Communicating
science accessibly and attractively is an ever-growing priority for researchers worldwide. FameLab
helps young scientists acquire valuable skills to communicate their work to non-scientific audiences.
By doing so, researchers not only challenge common stereotypes of scientists, but also help to justify
public funding for their research.

Monte Carlo simulation of the NaI(Tl) detector response to measure activated
foils
Hamed Panjeh, Motahhareh Abbasi (Department of Physics, Faculty of Science, Guilan Univer-
sity, Rasht, Iran), Reza Izadi, John Kettler
This paper introduces a simulation method to predict the output pulse height tally of a gamma
detector for an active foil in a specific time after the irradiation. Monte Carlo technique based on
the MCNP-4C code was used for the simulations. A combination of two MCNP input files was per-
formed and joined to three FORTRAN programs. The Direct Simulation Monte Carlo code (DSMC)
was written and developed based on 5 steps. The developed code is straight forward, so that the
calculation time for analyzing the delayed gamma neutron activation is very short. The estimation
of the induced radioactivities in the foil by activation is the main goal of the work. Comparison with
the experimental results shows the simulation has been done well.
Kaon production in central Au+Au collisions at 30 A and 45 A GeV
Hamoud Alharbi (KACST), Hamad Alhendi, Masaud Almalki (KACST), Magdi Bajusair (King
Saud University)
Ultra-relativistic heavy ion collisions are used to study the confinement to de-confinement phase
transition state and the possibility to create quark gluon plasma (QGP). Strangeness enhancement
is considered to be one of traditional signature formation of (QGP). Kaons are the lightest strange
particles which are produced only at the time of collisions and thus are expected to carry important
information of collision dynamics. The production of Kaon mesons are investigated within the Ultra-
Relativistic Quantum Molecular Dynamics Model (UrQMD). The time evolution of average density
around the collision center is calculated at different collision times at 30 A and 45 A GeV. The time
of maximum compression can then be determined. The distribution of rapidity and transverse mass
are presented for Kaon mesons.

Instant form separable model for pion-nucleon system
Hamoud Alharbi (KACST), Turki Aloyayd
A separable Poincar´e invariant instant form model for the pion-nucleon system has been constructed.
It describes the coupling between single-baryon and meson-baryon channels. The elastic scattering
amplitudes are obtained from three-dimensional Lippmann-Schwinger equations. The S-matrix el-
ements for the various processes are gauge invariant and transform properly under inhomogeneous
Lorentz transformations. The mass-operator interactions that describe the meson-baryon processes
have been derived.
Calculation of gas gain for a MSPC detector
Okla AlHorayess (KACST)
Unlike Multi-Wire Proportional Counter (MWPC), the principle of Micro-Strip Proportional Counter
(MSPC) is that the anode and cathode electrodes are very narrow conductor strips. The field strength
necessary to produce gas amplification in MSPC is generated between neighbouring strips and by the
voltage difference between the strips and the detector cathode, which can be at considerable distance.
The application of some Single Wire Proportional Counter (SWPC) gain formulas to MWPC depends
on the radial symmetry of the electric field. In the MSPC, there is no such radial symmetry, and the
transformation is not possible. Therefore, application of a gas gain formula to MSPC need to take
into account the difference in MSPC geometry from that of SWPC and MWPC. In this study, the
Diethorn formula was used to calculate the gas gain in a MSPC filled with Xe+5%CO2at different
gas pressures. The results of the measured and the calculated gas gain were found to be in good
agreement.

Ozg¨ur Aytan (Istanbul Universty)
Sip test is a conventional technique for identifying defective fuel elements in water moderated nuclear
reactors. We performed sipping tests to examine fuel assemblies of TR-2 reactor, a 5MW open pool
type reactor, sip testing has been conducted at C¸ ekmece Nuclear Research and Training Center. In
our design, test equipment identifies leaking fuel rods by obtaining and measuring 137Cs that leak out
and captured by mixed type ion exchange resin beds of defective fuel assemblies. 31 fuel elements in
the reactor core have been tested for the clad integrity. The experimental value of the fuel element
with an identification number 104 S has a 10247 Bq/0,3 l 137Cs activity. This value is approximately
234 times greater than the core average value. Therefore, we argued that this fuel element clad is
ripped.
A Pulse Height Response Spectrometer for neutron detection based on digital
signal processing
Andrew Bolyog (Atomki, Debrecen), Andrew Fenyvesi, Joseph Molnar
Pulse Height Response Spectrometry (PHRS) is a tool of neutron physics and several applications
performed with fast neutrons with En>0.1MeV energy. We have built and characterized a PHRS
system based on a scintillation detector with EJ-301 liquid scintillator and Digital Signal Processing
(DSP). The system will be used for characterization of mixed neutron-gamma fields to be used for
applications at MTA Atomki (testing new types of neutron detectors, radiation hardness tests, etc.).
The photomultiplier of the scintillation detector is connected to a CAEN DT5751 digitizer (1 GS/s,
10 bit). Time stamp, short integration value, long integration value and the PSD (Pulse Shape
Discrimination) value [1] are recorded in list mode. 2D plot of the PSD value is used for separating
the events induced by protons and gamma photons. The gamma and neutron responses of the system
are studied experimentally and via Monte Carlo simulations. The Eg= 03 MeV gamma and the
En= 1−12 MeV neutron energy ranges are covered. Irradiations are done with quasi-monoenergetic
d+Dneutrons at the MGC-20E cyclotron of MTA Atomki. The measured and simulated gamma and
neutron response functions will be presented with the neutron spectra unfolded from the measured
proton spectra via a derivative unfolding method [2].

The neutron- deficient nuclides of 125,127Ba are theoretically studied and the level structures for high-
spin states is interpreted within the framework of the RMF model. The electron internal conversion
coefficients in the 125,127 Ba nuclides are calculated on basis of relativistic Dirac-Fock method. It
is performed a comparison of the obtained theoretical data and data by Rossel et al. [3], which
are 1.1×103and 8.5×104for M2 and E3, respectively, the 24-keV transition can be considered
mainly an M2 transition. The other aK values of the 79.4-, 114.3-, 128.7-, 134.3-, 220.4-, 243.0-,
253.3-,269.6-, 285.6-, and 318.7-keV transitions associated with the decay of 127La are deduced from
the electron internal conversion measurements [1]. The E1 transitions between parity doublets are
characterized by a two to four orders of magnitude enhancement compared to those of more normal
cases. A possibility of manifestation of stochastic elements (dynamic enhancement) and quantum
chaos is discussed.

Excitation rates for nuclear isomers in hot plasma and photon-plasmon tran-
sitions in positronium and astrophysical plasma
Vasily Buyadzhi (Odessa State University -OSENU), Tatyana Florko, Anna Ignatenko
The short-lived excited states of nuclei in a hot plasma with excitation energies on the order of the
temperature of the plasma reach thermal equilibrium with the nuclear ground state and their relative
population is determined by a Boltzmann distribution. These states are usually taken into sccount
in standard nucleosynthesis calculations, though the data about their nucleonic reaction properties
are not sufficient. The aim of our work is to study the rates for electromagnetic excitation of the
isotopes of several isomers of interest both in astrophysics and nuclear physics (235 U, 193Ir, 87,88 Y)
and photon-plasmon transitions in positronium. We use the consistent quantum approaches [1] to
estimate the key characteristics of the electromagnetic processes, namely, photo-absorption, inverse
internal conversion, inelastic electron scattering, Coulomb excitation etc. Further the photon-plasmon
transitions probabilities P(ph −pl)with emission of photon and Langmuir quanta in astrophysical
plasma are estimated. Our value P(ph −pl)is 5.3×1061/s, where U is density of Langmuir waves
energy. It is agreed with other estimates [2]: P(ph −pl)=6×1061/s.

Particle-number conservation in charge-radii of odd-mass proton-rich nuclei
in the isovector neutron-proton pairing case
Mohammed Fellah, Nassima Allal, Mohamed Douici (Facult´e des Sciences et de la Technologie,
Universit´e Djilali Bounaama, Khemis Miliana, Algeria), Mohamed Reda Oudih
In medium-mass nuclei close to the N=Zline, the neutron-proton (np) pairing correlations play an
important role. They are generally studied within the BCS approach, but the main shortcoming of
the latter is the particle-number fluctuation. A projection is thus necessary. Furthermore, the charge-
radius is one of the fundamental properties of atomic nuclei. Its study may provide useful information
about their size and shape. The isovector np pairing effects as well as those of the particle-number
projection on the charge-radii of even-even nuclei proton-rich nuclei have been recently studied [1].
The aim of the present contribution is to study these effects on the charge-radii of odd-mass nuclei in
the same region. As a first step, an expression of the projected quadratic charge radius is established
using the Sharp-BCS (SBCS) method [2]. It is shown that it generalizes the one obtained when only
the pairing between like-particles is considered. As a second step, the charge-radii of some odd-mass
nuclei are calculated using the single-particle energies of a Woods-Saxon mean-field. The obtained
results are compared to those obtained when only the pairing between like-particles is considered.

The stopping power calculation of water and lung for protons in radiotherapy
Rza Dilek (Dilek), YeS¸im ¨
Oktem
This study aims to calculate the energy losses in unit length of protons during their movement within
water and lung by using two analytical equations. One of the equations used in this study is the
mass stopping power equation suggested by Bethe-Bloch (1930-1933) and modified by Tsoulfanidis
(1995) and a new approach has been suggested in the other one.Sted in the other one. Methodology:
The suggested new approach was obtained by substituting effective z*, Z* and I* values into the
equation reported by Tsoulfanidis. Although the energy range of protons used in the radiotherapy
is 75-250 MeV, in this study 0.001-250 MeV energy ranges were performed to identify the stopping
power. In addition, a new empirical relation was given to simplify the expressions for stopping
power. The results were compared with the other researchers results.The suggested approach for the
mass stopping power (Equation 2) can be used for both high- and low energy protons. Stopping
power values of protons should be especially useful in such medical fields as radiobiology, biomedical
applications, radiotherapy and so on.

Isomeric Yield Ratio of 104,106m,gAg from natAg(γ, xn)reaction at end-point
bremsstrahlung energies of 50 and 60 MeV
Mansoureh Tatari, Mohammad Eslami-Kalantari (Faculty of Physics, Yazd University)
The isomeric yield ratio (IYR) of 104,106m,gAg in the 50 and 60 MeV bremsstrahlung induced reaction
of natAg has been determined for the first time by off-line gamma ray spectrometric technique using
100 MeV electron linac at Pohang Accelerator Laboratory (PAL), Pohang, Korea. The end-point
bremsstrahlung energies of 50 and 60 MeV were produced by impinging electron beam on tungsten
metal foil of thickness 0.1 mm and area 10 cm ×10 cm. The production of 104m,g Ag and 106m,g Ag
from natAg(γ , xn)reactions takes place from various reaction channels depending on the isotopic
composition and reaction threshold. Thus the correction due to the contribution from the higher
reaction channels were taken care by taking the help of TALYS 1.4 computer code to obtain the
absolute IYRs of 104,106m,gAg from natAg(γ, xn)reaction. The flux-weighted IYRs of 104,106m,gAg as
a function of bremsstrahlung energy were also calculated theoretically using computer code TALYS
1.4. The corrected experimental IYRs of 104,106m,g Ag obtained in the present work along with
literature data at lower energies are compared with the theoretical value from TALYS and found to
be in general agreement. It was observed that the experimental and theoretical IYRs of 104,106m,gAg

How LiF material can help to more convergence of neutron beam (J/φ) on the
tumor in BNCT ?
Zahra Ahmadi Ganje, Mohammad Eslami-Kalantari (Faulty of Physics, Yazd University, Yazd,
Iran)
In order to treatment of deep brain tumors, BNCT is a well method. BNCT consists of two steps.
First, 10B carrier drug is injected in the patient body, then the patient is irradiated with thermal or
epithermal neutrons. Recently, studying on production of neutrons by accelerators to use in BNCT
treatment is growing up. One of the famous reactions using accelerators beam for neutron production
is 7Li(p,n)7Be. The relatively low energy neutrons emitted from this reaction, enable us to use less
moderation. In this paper, a new BSA based on 7Li(p,n)7Be reaction for irradiation of 2.5 MeV
and 20 mA proton beam is proposed. This BSA consist of 20 cm D2O as a moderator, graphite
as a reflector, Cd as a thermal neutron filter and BeO as a collimator. The aim of this paper is
the increasing of neutron beam convergence (J/φ) by means of adding different thickness of LiF
layers to the end of configuration, while J/φhas already been satisfied for proposed BSA. Finally, a
simulated Snyder head phantom is used to calculate the dose distribution inside of tumor and healthy
head tissue have been calculated. It has been showed that the increasing of J/φ, as an important
parameter in the BNCT, lead us to have better performance of beam and survival of healthy tissue
surrounding the tumor. The Monte Carlo MCNPX code is used for presented results.
A new shock-capturing numerical scheme using an exact Riemann solver
Zuzana Feckova (Matej Bel University), Boris Tomasik
Hydrodynamic modelling of quark-gluon plasma requires sophisticated numerical schemes that have
low numerical viscosity and are able to cope with high gradients of energy density that may appear
in initial conditions. We propose to use the Godunov method with an exact Riemann solver for ideal
hydrodynamic modelling to meet these conditions. We present the results of numerical tests of the
method, such as the sound wave propagation and the shock tube problem, which show both high
precision of the method and low numerical viscosity.
Investigation of the effect of pulsed lasers and continuous lasers on the inverse
bremsstrahlung absorption in laser - fusion plasma
Narges Firouzi (Faculty of Physics, Yazd University, Yazd, Iran), Mohammad Eslami-Kalantari
Inverse bremsstrahlung absorption, (IBA), is the most efficient absorption mechanism in laser-fusion
plasma. IBA is the process where an electron absorbs a photon during of colliding to an ion or to
another electron. IBA of laser energy in homogeneous and unmagnetized plasma has been stud-
ied using the Fokker-Planck equation, f0. This equation is an isotropic q-non-extensive electrons
distribution function. Considering a circular-polarized laser wave and kinetic theory with the using
spherical coordinates we get f1that is anisotropic function, then absorption is calculable. A pulsed
laser is considered and effect of the physical parameters such as temperature and q (q is a parameter
quantifying the degree of nonextensivity) have been studied on the absorption value, then the results
are compared with continuous lasers. The calculations of IBA were performed for various q. In this
paper we can deduce from calculations, IBA in near of critical layer using continuous lasers is higher
than pulsed lasers, also absorption increases with q parameter and it decreases as the temperature
increases.

Single-particle states in neutron-rich copper isotopes
Louis Olivier, Pierre Morfouace, Serge Franchoo (IPN Orsay)
The behaviour of the shell structure for exotic nuclei is far from being well known. When going
far from stability, some old magic numbers can disappear and new ones can appear. We here
discuss about neutron-rich copper isotopes towards the 78Ni doubly-magic nucleus, with the strength
functions of the shell-model orbitals measured in the 72Zn(d,3He)71 Cu proton pick-up reaction in
inverse kinematics with a radioactive beam at GANIL in France. It shows that the Z= 28 shell gap
in the neutron-rich copper isotopes is not appreciably affected by the addition of neutrons beyond
N= 40. We also present the latest results from an experiment leading to selective population of
hole states in 79Cu, through the 80 Zn(p, 2p)79Cu knock-out reaction with the liquid-hydrogen target
MINOS, performed at RIKEN in Japan and being currently analysed.
Advanved quantum-mechanical approach in terms of collective coordinates in
theory of nuclear alpha-emission
Alexander Glushkov (Odessa University -OSENU), Yulia Dubrovskaya, Yulia Chernyakova, Lar-
isa Vitavetskaya
Paper goes on the systematic studying the cooperative nuclear processes [1] with some refinement of
the quantum mechanical description of the simple droplet nuclear model. The aim is to account for
the most important dynamics features of the inner-nuclear processes that must lead to simplification
of calculational procedure. Approach proposed must allow for systematic refinements in the frame
of the formally exact perturbation theory, based on the more fundamental theory of nuclear matter.
We consider a new consistent quantum-mechanical approach in terms of collective co-ordinates in
theory of nuclear alpha-emission. It is supposed that Hamiltonian of e-N system used by us can
be treated as the bare Hamiltonian in such a theory. It is important that the theory of the alpha
emission includes the main features of the general nuclear fission theory. The classical Hamiltonian
of the nuclear system is constructed accounting the Coulomb inner-nuclear interaction and strong
interaction approximated by the ”Yukava plus exponent” potential. The final form of Hamiltonian
accounts for some empirical information concerning the lowest alpha decaying state. As an illustra-
tion we present the preliminary results of the calculation for 210Po which shows a principal value of
the mass tensor character for spectrum of emitted alpha-particle.

Spectroscopy of the heavy quarkonia: energy levels splitting and relativistic
corrections
Alexander Glushkov (Odessa University-OSENU), Andrey Svinarenko, Georgy Prepelitsa, Tat-
yana Tkach
Experimental data on spectra of heavy quarks prove an existence of the quark spin dependent rela-
tivistic interactions, which are absent in the nonrelativistic potential models. There are experimentally
observed (in the radiative E1-transitions N3S1-N-13PJ-N-l3 S1) triplets 3PJof states with the split-
ting of dozens MeV (in charmonium and bottonium). The radiative M1 transitions between orto-
(3S1) and para- (1S0) states are also observed in the charmonium family. An adequate account of
relativistic effects is absolutely needed. We present a generalized relativistic model of quarkonium
spectra, which is based on the numerical solving the relativistic Dirac equation with the correspond-
ing QCD potentials. The total Dirac Hamiltonian contains a bare Dirac Hamiltonian with adding
the quark spin dependent Breit-Fermi operator and spin independent one. Naturally, the Hamilto-
nian is broken on Lorentz-scalar and Lorentz-vector parts. The problem of Lorentz structure of the
inter-quark potential provides a necessity of introducing a dynamical quark mass. The results of
estimating spectra for families of charmonium and bottonium, radiative E1 transitions and lepton
decay widths in charmonium are presented and compared with the results of other available potential
model calculations and experimental data. Besides, the results of calculation of energy levels splitting
in quarkonium in dependence upon the different form of the potential with teta-functional feature
are presented.
Spectroscopy and dynamics of hadronic atoms and heavy ions: energy shifts
and widths and strong interaction corrections
Alexander Glushkov (Odessa University -OSENU), Denis Sukharev, Inga Serga, Anastasiya
Shakhaman
Our work is devoted to spectroscopy and dynamics of hadronic (kaonic, pionic) atoms, heavy H-,Li-
like ions (test systems) within ab initio nuclear-relativistic manybody perturbation theory [1] with
accounting nuclear, radiative effects. One of the purposes is establishment a quantitative link be-
tween quality of nuclear structure modeling and accuracy of calculating spectra. The wave functions
zeroth basis is found from the Klein-Gordon-Fock equation for K-, π- atoms and Dirac-Fock for ions.
The potential includes SCF ab initio potential, the electric and polarization potentials of a nucleus
(the RMF and Gauss models for a nuclear charge distribution) [1]. The Lamb shift polarization part
is treated in the Uhling-Serber approximation and the self-energy part within the Green function
method. New dtata are listed on: i). Spectra of H-,Li-like ions (Z= 55 −100); 2). Shifts, widths
in kaonic K-atoms (H, He, W, Pb, U); 3). Shifts, widths n π-atoms (H, He, W, Pb, U)

Nurg¨ul Hafizo˘glu (Istambul University), Latife S¸ahin YalC¸ in, Kaan Manisa, Hakan Cetinkaya,
Engin Bozkurt, Serap Bostan, Ahmet Bicer
All living organisms on earth are exposed to natural radiation because of the earths radiation. Natural
external radiation consists of cosmic rays and terrestrial radiation. Terrestrial gamma radiation, to
a large extend comes from natural radionuclides in the soil, i.e. the 238 U, 232Th and 40 K. Cosmic
rays are the radiations from outer space to the earth. In this study, 238 U, 232Th and 40 K activity
concentrations of 355 soil samples collected from the center of K¨utahya, counties and towns were
determined by using NaI(Tl) detector. The gamma dose rates in air were measured from a height
of 1 m µR/h as in the unit of by Ludlum 2241-3RK portable handheld detector at the points where
the samples were collected. By using gamma dose rates in air and in the soil, the annual effective
dose values were calculated for the city of K¨utahya. At the end of our study, 238 U, 232Th and 40 K
activity concentration and effective dose values calculated for radioactive nuclei were compared with
UNSCEAR and studies that have been performed for various parts of the world.
Semileptonic decays of B,Bsmesons with Klein-Gordon equation and Cornell
interaction
Hassan Hassanabadi (University of Shahrood), Sara Rahmani
Applying Klein-Gordon equation with Cornell interaction and considering of linear term as parent
we find the mesonic wave function in terms of Airys functions. We then calculate the decay width,
branching ratio and the CKM matrix element for semileptonic decays of Band Bsmesons using
Isgur-Wise function formalism. Comparison with other models is also included and motivating.

At the new facility built at GSI Darmstadt (Germany) will be performed a large variety of nucleus-
nucleus collisions at energies between 2 A GeV and 45 A GeV [1]. One of the detection systems that
will use it is CBM (Compressed Baryonic Matter). An interesting objective of the experiment is that
related to the phase transitions in nuclear matter formed in these conditions. The type of the phase
transition and the specific features are other interesting aspects. In the present work we will extract
basic information using antiparticle to particle ratios and thermal model predictions [2,3]. Search for
the critical point in connection with the increase of the fluctuations and with the rapidity range will
be done, too [4]. We use simulations with different codes (AMPT, UrQMD etc) done with the YaPT
system from the research center Nuclear matter in extreme conditions, Faculty of Physics, University
of Bucharest.

Isospin dependence of Spin-Orbit splitting in relativistic and non-relativistic
density functionals.
Konstantinos Karakatsanis (Department of Physics, Aristotle University Thessaloniki, Greece),
Peter Ring, Georgios Lalazissis, Elena Litvinova
One of the most important advantages of relativistic mean-field (RMF) models in nuclear physics is
the fact that the large spin-orbit (SO) potential emerges automatically from the inclusion of Lorentz-
scalar and -vector potentials in the Dirac equation [1]. It is therefore of great importance to compare
the results of such models with those of non-relativistic models and with experimental data. In a
recent experiment by Burgunder et al. [2] the isospin dependence of the level splitting between
spin-orbit partners has been studied by (d, p)transfer reactions in several isotones with neutron
number N= 21. Inspired by this work we carried out an investigation following the self consistent
approach of relativistic and non-relativistic energy density functionals describing these nuclei, in
particular 40Ca, 36S and 34 Si. Concentrating on the first 7/2-, 3/2-, 1/2- and 5/2- neutron states,
we calculate the SO splittings of the 2p and the 1f orbitals and compare them with the respective
experimental results. Our first approach is to calculate the single particle energies using a Relativistic
Hartree Bogolyubov code based on several modern nonlinear and density dependent covariant density
functionals with various pairing schemes. In the second step we use several non-relativistic Skyrme
and Gogny functionals to investigate the energy splitting for the same levels. Finally we study the
influence of tensor forces and of particle vibrational couplings on these spin-orbit splittings.
Electroweak interaction, parity nonconservation in heavy finite fermi-systems
and dynamical enhancement of weak interaction
Olga Khetselius (Odessa State University -OSENU)
Nowadays the PNC in the finite Fermi-systems has a potential to probe a new physics beyond the
Standard Model. We systematically apply our combined nuclear (relativistic mean field model) and
QED many-body perturbation theory method [2] to precise studying spin- independent and spin-
dependent (SD) PNC effects. There are listed new results of the calculating the nuclear magnetic
moments, hf structure, PNC amplitudes for a set of elements: 133Cs, 137 Ba+,205Tl, 223 Fr, 173Yb with
account of the exchange-correlation, Breit, weak -e interactions, radiative, nuclear (magnetic moment
distribution, finite size, neutron skin) corrections. Comparison with the SM and other data [1] is done.
As exciting example we list our QW value of 173Yb QW =−92.31 [the PNC amplitude 9.707 ×
10−10iea] that differs of the SM QW =−95.44. The nuclear SD PNC interactions due to nuclear
anapole moment, Z-exchange interaction from nucleon axial-vector (AnVe) currents, the combined
hyperfine and spin-independent Z-exchange interaction from nucleon vector (VnAe) currents are
computed. In quantum many-body systems with dense spectra of excited states weak perturbation
can be significantly enhanced. The PNC enhancement is studied too and new possibilities are
examined.

Stochastic features of decay of the multipole giant resonances in nuclei
Olga Khetselius (Odessa University -OSENU), Andrey Svinarenko, Yulia Dubrovskaya, Ludmila
Lovett
We present generalized multi-configuration model to describe a decay of hmultipole giant resonances
(MGR), which is based on shell model and microscopic model of pre-equilibrium decay with statistical
account for complex configurations within generalized Zhivopistsev-Slivnov model [1,2]. All possible
configurations are divided on two groups: i) complicated configurations, which are considered within
shell model with account for residual interaction; ii) statistical group of complex configurations
with large state density and strong overlapping. To account for collectivity of separated complex
configurations for input state a diagonalization of residual interaction on the increased basis (ph, ph+
phonon, ph+2 phonon) is performed. Process of arising a collective state of MGR and an emission
process of nucleons are described by the corresponding diagram with V effective Hamiltonian of
interaction, resulted in capture of muon by nucleus with transformation of proton to neutron and
emission by antineutrino. Isobaric anagoges of isospin and spin-isospin resonances of finite nucleus
are excited. Proposed model of MGR decay is applied to analysis of reaction (-n) on nucleus 40Ca.
The residual interaction was chosen in form of Soper force. Our data are compared with experimental
data and other calculation data.

Relativistic energy approach to cooperative electron-gamma-nuclear processes:
NEET effect
Olga Khetselius (Odessa University -OSENU), Anna Kvasikova, Tatyana Florko, Andrey Smir-
nov
Consistent relativistic energy approach (REA) to calculation of the cooperative electron-gamma-
nuclear processes combined with the relativistic PT [1] is presented. The nuclear-excitation electron
transition (NEET) effect is studied. The NEET probability is determined as the probability that
decay of the initial excited atomic state will result to the excitation of and subsequent decay from
the corresponding nuclear state. Within REA the probability is connected with an imaginary part
of energy shift for the system (nuclear subsystem + electron subsystem + photon) excited state.
The effects of purely nuclear transition, purely electron-(hole) transition and combined electron
nuclear transition can be distinguished. The calculation results are presented for the atomic/nuclear
systems 189Os,193Ir, 197 Au, 235U and compared with available theoretical and experimental data [2].
Studying the cooperative electron- gamma-nuclear process such as the NEET effect is expected to
allow the determination of nuclear transition energies and the study of atomic vacancy effects on
nuclear lifetime and population mechanisms of excited nuclear levels.

Nadezda Kornegrutsa (JINR), Denis Artemenkov
The BECQUEREL project [1-3] at the JINR is devoted systematic exploration of clustering features
of light stable and radioactive nuclei. Stacks of pellicles of nuclear track emulsion provide a special
opportunity to explore clustering of light nuclei (reviewed in [1]). The presented results on dissociation
of 7Be nuclei are demonstrate the progress in research carried out by the BECQUEREL Collaboration.
The 7Be nucleus is a source for the study of the states 3He+4He, 3He+3He+n,6Li+pand 6Be+n.
The pattern of fragmentation is important for understanding of the structure features of the nuclei
8Be, 9C and 12N because the 7Be nucleus plays the role of a core in them. The obtained in this
experiment data are compared with the Geant4 and QMD simulation.

Exposures of nuclear track emulsion to light radioactive nuclei, neutrons, and
heavy ions
Nadezda Kornegrutsa (JINR), Denis Artemenkov
Nuclear track emulsion (NTE) stays to be a versatile and inexpensive technique for forefront re-
searches. In JINR samples of reproduced NTE have been exposed to 1.2 A GeV 11C nuclei, 7 A 8He
nuclei, thermal and fast neutrons and 1.2 A MeV Kr and Xe ions. NTE has retained its position as
a means for studying a nuclear clustering via relativistic fragmentation [1]. Using the ACCULINNA
separator 8He nuclei were implanted into NTE which allowed to observe a drift of 8He atoms and
to derive the distribution over decay energy Q2α. The established ”tail” of large values Q2αcould
allow one to examine a structure of the state 8
2Be+. Correlations of α-particles 12C→3αare studied
in NTE exposed to 14.1 MeV neutrons of the apparatus DVIN. Energy distributions Q2αand Q2α
indicate on superposition of the 8Be 0+and 2+states in the 12 C ground state at that 8
2Be+is
dominating. NTE enriched with boron is exposed to thermal neutrons at the reactor IBR-2 allow one
to extend range calibration for the 7Li nucleus using events nth + 10B→7Li+γ) + α. Angular and
energy correlations of the reaction products are studied. There is a prospect of an NTE application
in physics of a ternary fission. It is necessary to perform range calibrations and to estimate of angular
resolution for an available variety of heavy ions.

Deuteron stripping on nuclei at intermediate energies
Valery Kovalchuk (Department of Physics, Taras Shevchenko National Univ. of Kiev, Ukraine)
A general analytical expression for the double differential cross section of deuteron stripping reaction
on nuclei at intermediate energies of incident particles was obtained in the diffraction approximation
[1]. Nucleon-nucleus phases were calculated in the framework of Glauber formalism and making
use of the double-folding potential. The exact wave function of deuteron with correct asymptotics
at short and long distances between nucleons [2] was used. The formalism used in ref. [1] was
later modified to calculate the nucleon polarization that arises in deuteron stripping reaction. The
calculated angular dependencies of cross sections and analyzing power Ayare in good agreement
with corresponding experimental data [3,4].

Using the nuclear diffraction model and the high-energy approximation with double-folding potential
based on CDM3Y6 interaction [1], the observed cross sections of quasi-elastic scattering of 6He, 7Be,
and 8Be nuclei by 12C nuclei at intermediate energies were described. The calculations performed
using realistic nucleon density distribution for target nucleus [2]. Moreover the Coulomb interaction
and inelastic scattering with excitation of low-lying collective states of the target [3] were taking
into account. The calculated angular dependencies of cross sections are in good agreement with
corresponding experimental data [4,5].

Universal Gamow line for even-even superheavy nuclei
S. Santhosh Kumar (Bharathidasan Govt. College for Women, Puducherry, India), A. Victor
Babu, P. Preetha
The existence of long lived superheavy nuclei (SHN) is controlled mainly by spontaneous fission
and alpha decay processes. The systematics of α-decay lifetimes formulated by Geiger and Nuttall
empirically formed straight lines. The half-life is extremely sensitive to Qα. Almost all the theories
use either the extrapolated values of Audi et al., or the measured KE to calculate the experimental
Qαexp in the calculation of T α. We proposed a corrected formula for Qα(cf∼ln2) for the SHN
which gives a very close agreement of the Qαexp. The earliest systematics of α-decay lifetimes of
natural emitters from actinides region was obtained by plotting the experimental values of log10T α
vs Qα −1/2and the data for a given Zd value fall roughly on a straight line with a large scatter
between the lines. To reduce this separation, Zd is incorporated with the Qα and hence log10 T α
vs Zd ×Qα −1/2plot became a better plot for half-lives since the lines for different Zd values
have a common slope. The universal straight line drawn by Silisteanu et al for 90 even-even SHN
from Zd = 100 −118 (rms = 0.1257) and from Zd = 102 −120 (rms = 0.4187). Our modified
Qα in the log10T α (Viola-Seaborg) and (Brown) formula shows the rms value of 0.2252 and 0.0007
respectively. Hence the Brown Formula fit with our modified Qα may be the best fit for future
studies of new alpha emitters in the superheavy region.

nuclear trace detectors were placed to 25 schools in Fatih District and they stayed there for a month-
period. After a month, the detectors were collected gently and the traces which occurs via basic
alpha decay on detector material, counted by using a special method for that special type of LR 115
detectors. According to the results of investigations, it was that the radon concentration varies be-
tween 40−395 Bq/m3. Our results are lower compared with Turkeys limits (400 Bq/m3) conversely
the results are higher compared with WHOs limits (100 Bq/m3).

Unified description of photo and electro processes on light nuclei in covariant
approach with exactly conserved EM current
Pylyp Kuznietsov (Institute of Electrophysics and Radiation Technologies NAS of Ukraine),
Yurii Kasatkin, Vyacheslav Klepikov
We use covariant approach with conserved EM current, which gives the ability to include strong
interaction into QED. Therefore, we receive the ability to describe disintegration processes on non-
local matter fields applying standard Feynman rules of QED. Inclusion of phase exponent into wave
function receives a physical sense while we deal with the dominance of strong interaction in the pro-
cess. We apply Green’s function formalism to describe disintegration processes. Generalized gauge
invariant electro-break up process amplitude is considered. One is a sum of traditional pole series and
the regular part. The deposits of regular part of amplitude, and its physical sense, are explored. A
transition from virtual to real photon considered in photon point limit q2seeks to zero. The general
analysis for electro-break up process of component scalar system is given. Precisely conserved nuclear
electromagnetic currents at arbitrary q2are received.
Thermonuclear reaction rates in rp process of sd shell nuclei
Yek Wah Lam (Inst. of Modern Physics, Chinese Academy of Sciences), Nadezda A. Smirnova,
W. A. Richter
Using the newly constructed isospin non-conserving (INC) shell-model Hamiltonians, we have derived
a new set of resonant and non-resonant (direct capture) contributions to radiative proton-capture
reaction rates on sd shell nuclei important for astrophysical rp process, namely, 23Al(p, γ)24Si,
25Al(p, γ )26Si, 28P(p, γ)29S, 29 P(p, γ)30 S, 35Ar(p, γ)36K, 31 Cl(p, γ)32 Ar and 32Cl(p, γ )33Ar. The
INC Hamiltonian is a combination of an isospin-conserving Hamiltonian, Coulomb interaction and
effective isospin-symmetry breaking forces of nuclear origin. The advantage is that Coulomb effects
are taken into account with great care, thus the approach allows us to predict unknown nuclear
level schemes and to describe decay modes more accurate than the traditional shell model. We
confirm that proton capture on excited states of some target nuclei may noticeably contribute to the
total rp process rates, e.g. 32 Cl(p, γ)33 Ar and 31Cl(p, γ )32Ar. We compare our results with previous
shell-model calculations and with estimations provided by currently available statistical model.

This paper presents an algorithm for the calculation of internal and external doses, which is an integral
part of the mathematical model of atmospheric dispersion. Results of modeling were compared with
values from an IAEA publication for a given scenario of radionuclide emission to the atmospheric
boundary layer. Due to small differences in the results, compared to the IAEA recommended model,
model presented in the paper can be used as a basis for this type of analysis. In order to illustrate
the application of this mathematical model using data of the hypothetical emission of radionuclides,
ventilation parameters, then 3D topography and meteorological data, field of total annual dose
received by a hypothetical resident in the vicinity of the reactor, during its routine operation over one-
year period is presented. This study presents fields of activity concentration in air, deposition on soil
and field of total annual dose to a hypothetical resident in the vicinity of nuclear reactor,contaminated
by air. In the analysis is used computer code based on straight line Gaussian model for atmospheric
dispersion, under conservative assumptions about the continuous operation of nuclear reactors and on
the strength of the source based on the inventory of radionuclides that are for one year continuously
emitted into boundary layer of the atmosphere. Based on this results, it can be concluded that a
nuclear reactor, under stated conditions of its operation, could not influence the environment above
the limit values of 10 µSv.

Application of the Direct Matrices Multiplication method in gamma ray spec-
trometry

Mirjana Djurasevic, Aleksandar Kandic, Ivana Vukanac, Bojan Seslak, Zoran Milosevic
The Direct Matrices Multiplication (DMM) method was developed by D. Novkovi as theoretical model
for coincidence summing of X-and gamma rays of radionuclides with complex decays schemes. This
method enables: a) identification of all possible decay paths and decay paths outcomes; b) calculation
of particular path outcome, probabilities and corresponding energy deposited in the detector; c)
determination of theoretical expressions for count rates of single and summing peaks as well as
for total count rate, where the unknown quantities are the total and peak detection efficiencies.
This method can be applied to the point sources and for small source-to-detector distances. It
was successfully applied to the decay of 139Ce, 57Co, 133 Ba, and 75Se. The DMM method was
tested on the equivalence with other methods for calculation of coincidence summing corrections
by G. Kanisch, T. Vidmar and O. Sima and a good agreement with the GESPRECOR program was
confirmed for point sources of 133Ba, 134 Cs and, 152Eu. In the case of the volume sources, calculations
of coincidence summing corrections, peak and total efficiencies are more complex than for point
sources. Laboratory for Nuclear and Plasma Physics participated in the intercomparison, organized
by the Gamma-ray Spectrometry working group of the International Committee for Radionuclide
Metrology (ICRM). Volume sources filled by radioactive solution (152Eu, 134Cs) and with different
absorbers have been considered. Results obtained by DMM method showed satisfactory agreement
with the mean values.
Heat capacity and level density of 94Mo nuclei using modified Ginzburg-
Landau theory
Ali Akbar Mehmandoost-Khajeh-Dad (University of Sistan and Baluchestan), Vahid Dehghani
A modified version of Ginzburg-Landau theory of phase transitions is presented, which seems to be
applicable to small systems, such as a nuclei. The effect of statistical fluctuations are taken into
account. The changes in the results are compared with the standard Ginzburg-Landau theory. We
have used this modified version + Fermi gas model in order to calculate the heat capacity and the
level density of the 94Mo nuclei. Our results show that this theory reproduces the experimental data
qualitatively. Since we take the effect of the statistical fluctuations into account we expect that the
order parameter does not vanish at a specific temperature, as in the small systems, which is in a
good agreement with our results.

The recently improvements and developments at the classic 9 MV FN Tandem are described in the
following work, together with the newly installed 3 and 1 MV Tandetron machines. The new slit
stabilization system for the ion beam energy based on interconnection of three signal types coming
from GVM (Generator Volt Meter), image slits and CPU is presented. An important development
in our laboratory was the design and construction of an alpha particle ion source, which is also able
to deliver other species of ion beams (H, S, O, N, F, C). The project involved the construction of a
charge exchanger based on Na vapors. Beside this, we report the first scientific results at the newly
installed last generation HVEE Tandetron accelerators. The 3 MV machine is dedicated to ion beam
studies and materials modifications, while the smallest one, the 1 MV accelerator is dedicated to
AMS (Accelerator Mass Spectrometry) and especially to radiocarbon dating.

Quantification of chromatic integration of painted panel
Maria Catalina Ghinea, Ioana Stanculescu, Constantin Daniel Negut, Octavian G Duliu
Using physical chemical techniques for investigation, conservation and restoration of works of art is
unavoidable nowadays. Nuclear techniques are among the most sensitive methods of elemental and
isotopic analysis. In this work Raman and Visible reflectance spectroscopy were used for quantifica-
tion of the chromatic integration which is the key operation in conservation restoration process with
the ability to enact the original aesthetics. Through scientific investigation, the color integration
process becomes a method of objective aesthetic restoration providing the working parameters: the
nature of the pigments and the surface application mode. Experimental panels with various pig-
ments: raw Sienna, red ochre and burnt umber applied in several layers were analyzed. Accelerated
aging and gamma irradiation of the wooden panels were performed to follow the stability of the
watercolors in time. Raman spectroscopy was used to determine the chemical composition of wa-
tercolors used in conservation-restoration and in conjunction with visible reflectance spectroscopy to
quantify the chromatic integration. Obtaining spectral parameters-pigment concentration calibration
curves allowed the interpolation of data obtained from the original panel with those obtained from
the experimental panels. This work was supported by an IFA-CEA grant, contr. no. C3-05/2013.

On-going gamma radiation processing for disenfection and consolidation of
cultural heritage

Cultural heritage represents one of the most important factor for human kind. First, it is the legacy
translated into accomplishments that people have made along their history, a thing that human
kind can be proud of and a reason for continuous development. Last but not least, it shows the
level of civility and progress reached along its existence. Considering this, salvation, consolidation
and preservation of cultural heritage become a mandatory objective. Cultural heritage is ineffably
degrading due to physical, chemical and biological factors. If physical and chemical degradation
can be delayed by controlling the storage conditions, the biological attack, once installed, can be
stopped only by a drastic intervention. IRASM department continuously dedicates a part of its
activity to this subject, dealing with different materials such paper, wood, textile and even leather
and parchment. Here, it is used ionizing radiation, a treatment that has the advantages of: the
certainty of biocide effect, fast treatment, mass treatment, no harmful chemicals and residues. The
research is conducted within projects and collaborations with Romanian museums and private holders
of artifacts.The aim of this paper is to present the recent activities and progress that IRASM has done
in this field, basically on wood consolidation, leather and textiles. Nevertheless, along with progress
new challenges rise, one determined by the complexity and diversity of the constituents of cultural
heritage items, that lead to the question if the radiation induces a supplementary degradation in the
material.

Gamma irradiation for material testing

Engineering (IFIN-HH)), Mihalis Cutrubinis, Ion Bogdan Lungu, Alexandru Alistar, Cosmin
Pintilie, Mihaela Manea, Ioan Valentin Moise
Radiation resistance of materials is of great interest for various industries such as medical devices,
nuclear power plants or aerospace. Among many types of radiation currently used for material testing,
gamma is the most common because of its high availability in research or industrial irradiators,
well standardized dosimetry, high reproducibility of the irradiation experiments. There are a couple
of irradiation parameters not easy to achieve in any type of gamma irradiator. Dose rate is a
parameter not commonly taken into account, but essential for testing certain materials such as
coatings used in nuclear power facilities. Dose uniformity ratio is the other parameter required by
certain standards, but often neglected in the published papers. IRASM Department of IFIN-HH
acquired a long experience in setting up gamma irradiation for different materials. It operates two
Co-60 gamma irradiators: a research, self-contained one (IAEA Category I dry storage), and an
industrial, versatile, panoramic irradiator (IAEA Category IV wet storage) which can operate in both
batch and continuous mode. In this paper, we present dosimetry data obtained from irradiation of
samples in wide dose and dose rate ranges, as well as several experimental set-ups for irradiation of
materials used in medicine, energy (nuclear power plants) and aerospace.
Testing of materials for nuclear physics experiments

Silvana Vasilca, Daniela Lungu, Valentin Moise
The materials used in nuclear physics experiments are of interest for two aspects: the behaviour in
time (degradation and ageing of materials used in the construction of the nuclear facilities) and the
purity of the materials used in certain experiments. A large number of testing methods are currently
available, with different degrees of standardization. The physics and chemistry testing laboratory
from IRASM Department of IFIN-HH performs radiation-hardness testing and characterization of
materials: thermal analysis (TG/DSC), mechanical testing, chromatography (GC-MS), vibrational
spectrometry (FT-IR/FT-Raman). The present work describes testing the purity of materials by
Inductively Coupled Plasma Mass Spectrometry (ICP-MS). In ICP-MS testing, two important steps
are defining the reliability and accuracy of the method: digestion of the samples and calibration.
The digestion procedure and equipment calibration are described in detail. Experimental results are
presented for the analysis of some ion excange resins (up to ppt).

FTIR/FT-Raman spectra and colour shifts used to study gamma irradiated
experimental models of painting
Mihaela Manea, Constantin Daniel Negut (Horia Hulubei National Institute of Physics and Nu-
clear Engineering (IFIN-HH)), Marian Virgolici, Ioan Valentin Moise
Color changes and other modifications in the physical chemical properties of materials induced by
gamma irradiation are feared by cultural heritage responsible committees and they have to be evalu-
ated objectively and precisely (Manea et al. 2012). The present study follows the changes of gamma
irradiated experimental models of painting with non-destructive and non-contact spectroscopic ana-
lytical techniques which are the only ones accepted by the conservators/restorers community. Molec-
ular structure characterization was performed by FTIR/Raman spectroscopy using a Bruker Vertex
70 class equipped with two mobile probes: a MIR fibre module for MIR probes (with LN2cooled
detector) and a Raman RAM II module (LN2 Ge detector) with a RAMPROBE fibre. Colour was
measured by a portable reflectance spectrophotometer (Miniscan XE Plus, HunterLab) in diffuse/8◦
geometry with a beam diameter of 4 mm and specular component included (Manea et al. 2014).

Radiation resistance of some microorganisms involved in cultural heritage
artefacts degradation

Ionizing radiation is used for decades in applications related to microbiological decontamination. Al-
though the study of radiation resistance of microorganisms started many years ago, in practice, a
number of aspects still need clarification. Some applications (like sterilization of medical devices)
have a high degree of standardization, while for others the radiation resistance tests are required for
each category of materials. One particular field, which requires careful evaluation of the radiation
resistance of a contaminating population, is the irradiation treatment for disinfection of cultural her-
itage artifacts (paper, wood, textiles, leather or complex combination of materials). Two aspects are
hindering the wide standardization of the irradiation practices: the large variety of microorganisms
encountered in various applications and the different radiation resistance reported for different envi-
ronmental or growth conditions of microorganisms. In this study there are reported the experimental
approaches for radiation resistance developed in the microbiological laboratory of IRASM department
from IFIN-HH, Romania. Experimental results were obtained in two applications on current interest:
standardization of the radiation resistance testing methods and irradiation treatment for cultural
heritage preservation. Previous studies showed that microorganisms resistance to ionizing radiations
does not significantly varies with storage conditions (temperature and humidity) preceding the irradi-
ation. Consequently, has been studied the radiation resistance of the same species of microorganisms
isolated from cultural heritage artefacts of different types (paper and textiles) and different origins.
The results aim to set the right treatment dose for the main decaying biological agent, in order to
stop the attack. The issue of non-cultivable microorganisms is also discussed.

Cross section measurement of the astrophysically important 17O(p, γ)18 F reac-
tion with the activation method

The 17O(p, γ )18F reaction is one of the most important reactions of astrophysical interest. In general
the hydrogen burning of oxygen isotopes can occur in hydrogen core and shell burning, asymptotic
giant branch (AGB) stars during hydrogen shell burning, intermediate-mass AGB stars during hot-
bottom burning, and both CO and ONe classical novae during explosive hydrogen burning [1]. This
particular reaction is a corner stone of the CNO-III and CNO-IV cycles that occurs mostly at massive
stars. Due to its astrophysical importance it is necessary to improve upon the existent data about
this reaction, especially at higher energies where only one experimental dataset is available [2].
The experiment is in progress at the new tandetron accelerator at the Atomki institute in Debrecen,
Hungary, where targets of Ta2O5where activated with a proton beam in the 500 keV to 2 MeV energy
interval. In this work we shall present preliminary results for the cross section of the 17O(p, γ )18F
reaction.

Preliminary considerations for production of radioisotopes by photonuclear
reaction using ELI-NP γ-ray beam
Dana Niculae (Horia Hulubei National Institute for Physics and Nuclear Engineering, Magurele,
Romania), Wen Luo, Dan Mihai Filipescu, Ioana Gheorghe, Dimiter Balabanski (Horia Hulubei

A very brilliant, intense γ-beam, which is produced by incoherent Compton back-scattering of direct
laser light with a very brilliant and intense electron beam, will become available at the upcoming
Extreme Light Infrastructure - Nuclear Physics facility (ELI-NP). Such facility will deliver a very
intense, brilliant γ-rays, ≤0.5% bandwidth, up to 19 MeV and hence provides an unprecedented
possibility for the production of radioisotopes in sufficient quantities for nuclear medicine research.
We present the isotope production photonuclear reaction schemes and cross-section simulations
under realistic conditions. We have to deal with reaction cross-sections as low as 0.1 barn for (γ, n).
We discuss the production of a key medical radionuclide, 99Mo/99mTc, and particularly focus on
the investigation of new radioisotopes including 186 Re, 64Cu and 225 Ra/225Ac for nuclear medicine
applications. The optimal conditions for generating medical radioisotopes with high specific activities
are found, and estimate to be produced in sufficient quantities for such research. This simulations
will be used in target design and also for radiochemical processing experiments with the view for the
potential clinical applications of radioisotopes.

Investigations of alternative, non-reactor based routes for production of 99mTc
Radu Leonte (Horia Hulubei National Institute for Physics and Nuclear Engineering, Magurele,
Romania), Dimiter Balabanski, Dana Niculae (Horia Hulubei National Institute for Physics and
Nuclear Engineering, Magurele, Romania), Lidia Matei, Richard Johnson, Wen Luo
Alternative methods for producing the medical imaging isotope 99mTc are actively being developed
around the world in anticipation of the imminent shutdown of the NRU reactor in Canada and the
Petten reactor in Holland that together currently produce up to 80% of the worlds supply through
fission. The most promising alternative methods involve accelerators that focus Bremsstrahlung
radiation or protons on metallic targets comprised of 100Mo. 100Mo(p, 2n)99mTc provides a direct
route to produce 99mTc, while 100 Mo(γ, n)99 Mo has to be followed by radiochemical processing.
Production of 99 Mo by bremsstrahlung radiation is achieved with limited specific activity that becomes
even more difficult to use with current technology used generators. Usingγbeams with high flux
density, 99 Mo can be produced with much higher specific activity, consistent with current technology.
Such beams can be used to pump a good fraction of the nuclear ground state population via excited
levels into an isomeric state. Using the new beam facilities compact targets could be exposed
to the gamma radiation and undergo photonuclear reactions to form radioisotopes that can be
incorporated into routine production in regional centres. All of alternative routes has to reconsider
the radiochemical processing employing gel-generator technology or thermal separation. Preliminary
results on (p, 2n)reaction and post-processing and simulations on (γ, n)route will are presented.
Parity non-conservation effects on slow neutrons capture by Lead nucleus
Ioan Oprea, Cristiana Oprea (JINR)
More than thirty years ago high values of parity violation (PV) effects in comparison with theoretical
evaluations in the scattering of slow neutrons experiments on Lead nucleus were observed. From
scattering experiments resulted that the main contribution to the PV effects is given by the 204Pb
isotope of Lead. Further in order to solve the discrepancy between theory and experiment on PV
effects it was supposed the existence of a new so-called negative neutron P-resonance. In one of our
previous work we have evaluated the PV effects on 204Pb isotope and using the existing experimental
data the weak matrix element was extracted. With some uncertainty we demonstrated the possibility
of the existence of a new P-resonance near the neutron threshold. Then we concluded that are
necessary new data on PV effects in nuclear reactions induced by slow neutrons and one of the most
convenient is the capture of the slow neutrons. In this work the asymmetry of emitted gamma quanta
was evaluated in the frame of the formalism of the mixing states of the compound nucleus with the
same spin and opposite parities. Combining the scattering and capture experimental and theoretical
data it is possible first to extract the weak matrix element of PV process and the answer to the
question of the existing of a new neutron P-resonance. The present theoretical evaluations on PV
effects in nuclear reactions by slow neutrons are dedicated to the preparation of new measurements
at IREN (Intense Resonance Neutron), a neutron source of LNF-JINR.

Developing of a RBS-Channeling system for crystallographic analysis at the
3 MV Tandetron Accelerator of IFIN-HH, M˘agurele - Romania
Doru Pacesila (IFIN-HH), Dan Gabriel Ghita
Ion implantation technology provides the most efficient way to insert impurities into different mate-
rials, especially materials with crystalline structure, in order to change in a controllable manner their
physical, chemical or electrical properties. It is a material engineering process that allows creation
of new materials, atomic mixing, metal finishing, etc. However, by implanting energetic ions into
crystals, one produces many point defects in the target crystal, such as vacancies and interstitials.
Thermal treatment can be performed to regenerate the crystal. The 3 MV Tandetron Accelerator
at IFIN-HH has a beam-line for ion implantation and can be used as a high-energy ion industrial
implanter on full-sized 225 cm2wafers. After, implantation analysis can be made to check for
induced crystal damage. We have developed an RBS-Channeling analysis system to allow quality
control check of implanted crystals. The system is fully-automated and it first seeks the crystal major
axis and then look for defects. Studies of crystalline structure can also be performed and we can
investigate crystal lattices in the bulk region.
Excitation of isomeric states in reactions (γ, n)and (n, 2n)on 45 Sc, 76Ge and
81Br
Satimbay Palvanov (National University of Uzbekistan)
This work presents work results of investigation of the isomeric yield ratios η=Y m/(Y m+Y g)of the
45Sc(γ , n)44m,gSc, 45Sc(n, 2n)44m,g Sc, 76 Ge(γ, n)75m,g Ge, 76Ge(n, 2n)75m,g Ge, 81 Br(γ, n)80m,gBr
and 81Br(n, 2n)80m,g Br reactions. The isomeric yield ratios were measured by the induced radioac-
tivity method. Samples of natural Sc, Ge and Br have been irradiated in the bremsstrahlung beam
of the betatron SB-50 in the energy range of 10-35 MeV with energy step of 1 MeV. For 14 MeV
neutron irradiation we used the NG-150 neutron generator. The gamma spectra reactions products
were measured with a spectroscopic system consisting of HPGe detector CANBERRA with energy
resolution of 1.8 keV at 1332 keV gamma ray of 60Co. The filling of the isomeric and ground levels
was identified according to their γlines. In the range 26-35 MeV the isomeric yield ratios Y m/Y g
of the reaction (γ, n)on 76 Ge, 82Se and 81 Br are obtained at first. Using the isomer yield ratio and
the total cross section of the (γ,n) reaction on Sc, Ge and Br we estimated the cross sections of
(γ, n)mand (γ , n)greactions. The cross section isomeric ratios at Eγ=Emare estimated. The
experimental results have been discussed, compared with those of other authors as well as considered
by the statistical model. Theoretical values of the isomeric yield ratios have been calculated by using
code TALYS-1.0.

analysis is Prompt Gamma Neutron Activation Analysis (PGNAA), with 252Cf as the neutron source.
A simulation study has been done to develop the setup geometry and investigate the possibility of
using other kinds of neutron sources as an alternative option. Application of neutron generators and
also (α, n)neutron sources in the PGNAA facility has been discussed.

Beam optic along the transfer RIB lines to the DESIR facility at GANIL-
SPIRAL2
Luc Perrot (CNRS/IN2P3/IPNO)
The new ISOL facility SPIRAL2 is currently being built at GANIL, Caen France. SPIRAL2 will
produce a large number of new radioactive ion beams (RIB) at high intensities. In 2019, the DESIR
facility will receive beams from the upgraded SPIRAL1 facility of GANIL (stable beam and target
fragmentation), from the S3 Low Energy Branch (fusion-evaporation and deep-inelastic reactions).
In order to deliver the RIB to the experimental set-ups installed in the DESIR hall, 110 meters of
beam line are studied since 2013. This paper will focus on the recent studies which have been done
on these transfer lines: beam optics and errors calculations, quadrupoles, diagnostics and mechanical
designs.
Algebraic models for shell-like quarteting of nucleons
Jozsef Cseh, Gabor Riczu (Institute for Nuclear Research, Hungarian Academy of Sciences)
We introduce two algebraic models for the shell-like quarteting of nucleons. The simpler one is based
on the quartet concept of Arima et al, which does not treat explicitly the degrees of freedom of
the constituent nucleons. Nevertheless, the Pauli-principle is not violated in this phenomenological
description, either: the quartets of four nucleons occupy different single particle space-states. The
semimicrosopic model is more detailed. It is based on the definition of quartets in terms of two
protons and two neutrons of [4] permutational symmetry. This model is able to take into account
0, 1, 2, 3, ... (nucleonic) major shell excitations, as opposed to the giant quartet excitations of the
phenomenologic approach, which correspond to 4q, q = 0; 1; 2; nucleon excitation quanta. For
both description the U(3) formalism of Elliott is applied for the calculation of the spectrum. Both
of these models are easy to apply, yet the semimicroscopic approach seems to be detailed enough to
account for a considerable amount of the experimental spectrum [1,2]. We expect that in addition
to its applicability to the s-d shell nuclei it can also be extended to the mass region of A= 92 −100
of current experimental interest.

Development of an external ion beam system for PIXE analysis
Adrian Rotaru (IFIN-HH), Dan Gabriel Ghita
Ion Beam Analysis (IBA) is a family of analytical techniques used for material characterization. It
probes a material for atomic composition and concentration along its surface and to depths of the
order of a few microns, depending on the type and energy of the probing beam. We have installed
at the Bucharest 3 MV tandetron a micro-beam scanning system that can use Rutherford back-
scattering(RBS), PIXE or PIGE to characterize surfaces. Either one or a combination of of these
techniques can give information about the elemental/isotopic composition and concentration across
surfaces. By using ion beams with diameters of a few microns we scan the surface of a target material
and determine atomic concentration maps with this resolution. The images we construct yield rich
detail and offer information about internal structure and composition, in particular for composite and
non-uniform materials. The characteristics for the setup are described with examples from typical
applications.

The 1S0channel in nucleon-nucleon nuclear Effective Field Theory
Mario Sanchez (Institut de Physique Nucl´eaire d’Orsay (IPNO))
A longstanding problem has been to obtain nuclear forces from the underlying theory of QCD. In
addition to allowing a derivation of nuclear structure, a first principles approach should provide
insight into the nature of the virtual state present in the 1S0nucleon-nucleon channel, which is
very near threshold and thus has an anomalously large, negative scattering length. This fact, which
is of relevance for nucleosynthesis and the abundance of the chemical elements in our Universe, is
presumed to be caused by fine-tuned cancellations, whose origin remains unknown up to now. QCD
at the energies of relevance for nuclear physics is described by Chiral Effective Field Theory, which
captures the most general dynamics among nucleons and pions allowed by the symmetries of QCD.
We present a systematic study of the different power countings that arise for the most important 1S0
effective range parameters in the context of a toy model consisting of the Yukawa part of one-pion
exchange, for a range of pion masses that includes the physical case. We also discuss the more
realistic situation in which additional short-range interactions play a significant role.
Calculating fission barrier and paths influenced by proton and neutron magic-
ity
Nafiseh Shayan Shakib (Payam-noor university), Radu Ghergescu, Dorin Poenaru
The macroscopic-microscopic method is used to calculate penetrabilities for different fission channels
around proton and neutron magic numbers from uranium and plutonium. The liquid drop part is
obtained from the Yukawa-plus-exponential potential, whereas the single-particle energy levels are
computed with the deformed two center shell model. The shell correction part is obtained by the
Strutinsky method, separately for protons and neutrons. Calculations are applied to the fission of
244Pu among different fission Channels.
