Abstract
We compare experimental triply differential cross sections for single ionization of He for small (100 MeV/amu C6+ projectiles) and large perturbation (3.6 MeV/amu Au53+ projectiles). For electrons emitted into the scattering plane at the small perturbation, the data are well described by our calculations. For the large perturbation as well as outside the scattering plane for the small perturbation, in contrast, serious discrepancies especially with the continuum distorted wave-eikonal initial state (CDW-EIS) model are found.
