Single ionization fully differential cross sections for 2 MeV/amu C6+ + He collisions are obtained and analysed using the classical trajectory Monte Carlo and continuum distorted wave models. The present theoretical results are compared with the recent experimental data of Fischer et al. The published experimental conditions are considered in both theoretical models. The inclusion of the momentum distribution of the target atom leads to an improved description of the forward electron emission. Dalitz plots for single ionization fully differential cross sections in ion-atom collisions are presented and are used to help elucidate the collision dynamics.
