The single ionizing collision with an incident electron and atom/molecules ends up two kinds of outgoing electrons called scattering and ejected electrons. As a feature of electron impact ionization these two electrons are indistinguishable. Double differential cross-sections can be obtained by the measurements of energy and angular distributions of one of the two outgoing electrons by a detector. In this perspective, we used He target that is reasonable to expect to understand ionization mechanisms of atomic systems. We have measured double differential cross-sections for asymmetric geometry for different kinematical situations. The experiments are carried out on a newly developed electron spectrometer constructed in Afyonkarahisar, Turkey.
