Post Collision Interraction Effect on the magnitude(e, 2e) Autoionization Amplitude

Abstract

Post collision interaction effect on the magnitude of the He(e,2e)He* direct and resonant amplitudes as a function of electron ejection angle has been considered. Calculated values are found in good agreement with the extracted experimental data. It is shown that the 3-body Coulomb interaction in final state may give a considerable contribution to the direct cross section, but a small account to the resonant cross section.
