Abstract

The production of Be2+(1s2) and hollow Be2+(2s2) in an (e,3e) collision between an electron and neutral Beryllium is studied theoretically. The variations of the fully differential cross sections (FDCS) of the two ionisation cases in terms of incident and ejection energies and detection angles are analysed. Aiming to probe electron-electron correlation, compact analytical wave correlated Jastrow functions satisfying Kato's cusp conditions are used for the four-electron Be initial state as well as for the two-electron Be2+ final states. The two ejected electrons are described by 3C correlated functions.
