Abstract

A new method for exciting high-lying states in oxygen molecules is proposed, which is based on the interaction of O2 molecules with a low-energy (∼102–104 eV) electron beam formed in a discharge with runaway electrons. An algorithm for calculating the electron energy distribution function (EEDF) using the Monte Carlo simulation technique is developed. The EEDF calculation for a discharge in pure oxygen is performed for a plasma pumped with monoenergetic electron beam in the absence of an external electric field. Efficiencies of the formation of Rydberg and Herzberg states in oxygen molecules under conditions of a quasi-stationary dc discharge and a discharge with runaway electrons are compared.
