Abstract

Cross sections for single electron emission have been measured in collisions of 95 MeV/u Ar18+ with atomic Li for electron energies 5-1000 eV and angles 25°-155°. The high projectile velocity made possible the separation of two- and three-body processes in the angular distributions of the ejected electrons. Low-energy emission of the 2s electrons is found to be significantly influenced by two-body effects and, furthermore, the node in the Li 2s wave function manifests itself in the angular spectra. Emission of 1s electrons is attributed mainly to three-body effects. The two-and three-body processes are associated with Compton scattering and photoabsorption, respectively.
