Abstract: An approach to the construction of models of ionization collisions of electrons with air plasma is proposed. The approach is based on the calculation of probabilistic distributions of energy losses by an incident electron during the ionization of plasma atoms and ions. The distributions are calculated by processing the impact ionization cross sections obtained in the distorted wave approximation. A model of individual collisions for a detail description of ionization processes in plasma and an approximate model of continuous slowing down allowing significantly simplify the calculations in the field of applicability of the model are constructed. The stopping powers of electrons in oxygen-nitrogen gas plasma are obtained.
Keywords: collisional ionization cross sections, model of individual collisions, continuous slowing down model.
