Abstract

For simultaneous projectile and target ionisation in He+He collisions the momentum distribution of the singly and doubly charged recoil ions has been measured. A new cold target recoil ion momentum spectrometer with a momentum resolution of ±0.13 a.u., based on a precooled supersonic He gas jet, has been used. The experimental doubly differential cross section shows two prominent structures which can be attributed to the two center electron-electron interaction and the nucleus-electron interaction. The contribution due to the electron-electron interaction is found to be negligible at 0.5 MeV impact energy and to be dominant at 2 MeV. The two center electron-electron interaction contributes much less to target double than to single ionisation. © 1995.
