Internuclear potential effects on the triply differential cross section for ion-atom ionization

Abstract

We present theoretical calculations of triply differential cross sections for electron emission in ion-atom collisions, including the internuclear interaction in a semiclassical approximation. We show that projectile double collision mechanisms can be taken into account in this way. We show the structures generated in the electron emission spectra by these processes, and suggest a way to experimentally verify them using recoil ion momentum spectroscopy techniques.
