Low-Energy Electron Emission in Fast Au53+ – Atom Collisions

Electron emission from multi-electronic target atoms by 3.6 MeV/uAu53+ ion impact is explored in kinematically complete experiments. DDCS as a function of the longitudinal and transverse component of the emitted electron momentum are in very good agreement with calculations using the CDW-EIS model. A study of the electron emission from specific sub-states shows that the initial state momentum distribution is mapped onto low lying continuum states with characteristic features which depend on the initial state wave- function.
