Abstract

Abstract:- This article describes the theoretical models for determination of electron-impact ionization cross-section, which has been applied to atoms, ions, and molecules. The model combines the Bethe theory and binary-encounter theory for electron-impact ionization called the binary-encounter Bethe (BEB) model that use the binding energy and average kinetic energy of each subshell that prescribes differential ionization cross section for that shell and S. P. Khare and co-workers give the new Formalism by combining Bethe and Mott's cross-section known as Jain-Khare Formalism are discussed here. Copy © 2017 Praveen Bhatt et al.
