Distortion effects for electron excitation in ion-atom collisions

Abstract

Electron excitation from monoelectronic targets by impact of bare ions from low intermediate to high collision energies is theoretically studied by using the symmetric eikonal approximation. In addition, multichannel semiclassical impact-parameter calculations are also carried out. Distortion effects introduced by the projectile charge are shown to appear in the theoretical models at low intermediate collision energies.
