Detailed studies on ionization of atoms and molecules by electron impact have made numerous contributions to understanding of the structure of atoms and molecules including the interaction between particles. After a ionizing collision a scattered electron, an ejected electron and a recoil ion is formed. Doubly differential cross-sections give detailed information for one of the outgoing electrons. In this study, we report the angular distribution of double differential cross-sections of ejected electrons from He in intermediate energy region.
