Probing Young-type interference effect on angular distributions of e-DDCS using fast electrons as projectile

Abstract

The energy and angular distributions of electron double differential cross sections (DDCS) of H2 and He are measured for fast electron collision.The measured data are compared with recently developed theoretical calculations. The observed distributions of H2 are explained in terms of interference effect by comparing with single center He and atomic hydrogen. We show experimentally by comparing with He, that partial constructive interference exists in soft and binary collision regions of H2 spectra.
