Electron DDCS in ionization of O2 by 4.5 MeV/u bare O-ions: A comparative study of the angular asymmetry between O2 and H 2

Abstract

We have measured double differential cross-sections (DDCS) of low energy electrons emitted from O2 in collisions with 72MeV bare O ions. The derived forward backward asymmetry parameter spectrum shows monotonically increasing behavior. No oscillation due to interference was observed in the forward-backward angular asymmetry unlike that for molecular hydrogen for which oscillation was unambiguous. © Published under licence by IOP Publishing Ltd.
