Energies of particles at the cathode of a glow discharge

A Monte-Carlo calculation has been carried out to obtain the energy distribution of ions and neutrals at the cathode of a glow discharge, assuming charge exchange collisions in different fields. The comparison with the previously studied case of linear field is good. Depending on the parameter L/lambda (ratio of length of cathode dark space to mean free path of atoms in the gas) the following information was obtained in addition: average number of collisions, relative contribution of number of collisions to the energy distribution, and average energy of the neutrals.
