Diffraction effects in binary encounter electron production from collisions of partially stripped ions

Abstract

A systematic investigation of binary encounter electron production from collisions of partially stripped ions with hydrogen and noble gases is currently under way. We present experimental double-differential binary encounter electron cross sections as well as model calculations for 0.6 MeV amu −1 Cu 19+, I 23+ and Au 29+ ions colliding with argon. The results show how, with increasing the screening of the projectile nuclear charge, quantum diffraction effects manifest themselves in the angular behaviour and shape of the binary encounter peak.
