Projectile scattering and electron-electron interaction in ion-atom collisions

Abstract

One- and two-electron processes involving electron transfer and excitation are considered for a few basic ion-atom collision systems at intermediate impact energies. We have used the two-center basis generator method in the framework of the independent electron model for orbital propagation and the eikonal approximation for the calculation of scattering-angle differential cross sections. Our results shed some light on the roles of the nucleus-nucleus and the electron-electron interactions in these collisions.
