Scattering of electrons is a fundamental phenomenon occurring either as a primary or secondary process whenever ionizing radiation interacts with matter. Energy deposition models, to study the interaction of radiation with matter and radiation damage, require scattering cross section data for all possible processes. Knowledge of electron scattering cross sections is therefore the most important and indispensable tool for the quantitative analysis of radiation impact phenomena. Electron impact ionization cross sections find practical applications in many branches of science viz. fusion edge...
