The energy and angular distribution of electron double differential cross sections (DDCS) in collision of 95 MeV F 9+ ions with molecular hydrogen have been measured. We explain the observed distributions in terms of the two-center effect and the Young-type interference effect. The asymmetry parameter, derived from the cross sections for complementary forward (30°) and backward (150°) angles, shows an oscillatory behavior as a function of electron velocity. The measured energy and angular distributions as well as the asymmetry parameter are compared with a molecular CDW-EIS (continuum distorted wave-eikonal initial state) theory.
