Soliton-like solutions in scattering of electrons by an ion in magnetized plasma

Scattering of an electron on positive and negative ions has been studied. The transverse electron motion is assumed to be suppressed by a strong magnetic field. Transferred energy is greater for scattering on a negative ion and shows a sharp peak for the impact parameter equal to the distance of the closest approach. It has been found that the motion equations have a soliton-like solution in this case. (paper)
