Effective scattering cross section vs. distance between the ions in the case of transverse incidence. The ions are located across the plane of incidence of the electrons. The computation parameters are Ω = 0.316 and v = (a) 1 and (b) 0.5.

Electron-ion collisions in a high-density plasma in strong electromagnetic fields are considered. The applicability condition
for the approximate model of pair collisions in strong fields are determined. It is shown that this condition is identical
to the condition for the plasma to be transparent. Investigations were carried out by the test partic...

... the mechanism whereby the electrons are turned backward in the case of quasi-transverse scatter- ing is unimportant, it should be expected that the main limiting size is r E . Numerical simulations confirm this conclusion (see Fig. 3). From Fig. 3 we can see that col- lisions become independent, σ σ 0 , at distances of ∆r ⊥ ≥ 2r E , regardless of the value of the electron drift velocity. For Ω = 0.1, the situation is similar. But since the computations are very involved, we carried out numerical simulations only for a few relative positions of the ...

The pair electron-ion collisions operator in strong electromagnetic fields is considered. In strong EM fields, the collision operator is derived allowing for the complex stochastic particle dynamics at the scattering. The resulting expression can be conditionally separated into the diffusion part (having a Landau-like operator form) and the fast-particle source.
