The problem of ionization and excitation pair prices in any gas medium can be solved by modeling the process of exchanging energy of the primary electrons with neutrals by Monte Carlo technique. The advantage of this method is that the physical processes of individual collisions of electrons are associated with a direct statistical analogy – branching random walk of a particle in a one–dimensional phase space. In this case, the transition probabilities are determined by the relevant integral cross sections of the processes of electron interactions with neutrals. This method allows a more complete analysis of the process, calculating as an average values of the characteristics of the interaction, and the time evolution of the electrons energy distribution.References
