Spectrum of prompt neutrons from fission of 235U(n, F) for En = 14.75 MeV (a) relative to a Maxwellian spectrum with average energy 2.13616 MeV: 1) [28]; 2) this work; 3) [4]; 4) [3]; D) [25] .
 Added PFNS calculated at 13 MeV and data from Kelly et al., EPJ Web of Conferences 239, 05010 (2020) for E_n=12-13 MeV. Shown calculated dotted curves for (n,f) reaction.

A new matrix of the spectra of prompt fission neutrons for the reaction 235U(n, F) has been obtained. The evaluated spectrum of prompt fission neutrons reproduces the measured data for incident neutrons with energy from thermal to 14.7 MeV. A solution is proposed for the problem of inconsistency of the integral testing of the systems with a thermal...
