Critical Comparison between Theory and Experiment for C⁶⁺ +He Fully Differential Ionization Cross Sections

Abstract

Fully differential cross sections for single ionization of helium induced by impact of 100 MeV/u C6+ ions are examined within a quantum-mechanical distorted wave model. The experimental uncertainties are included in the theoretical calculations, leading to a quantitative description of the experimental cross sections. In particular, the ionization cross section for the electron emitted in the plane perpendicular to the scattering plane is reproduced for the first time by a full quantum-mechanical model. The role of the internuclear interaction in this perturbative-regime collision is discussed and found to be unimportant for the present kinematical conditions.
