Abstract
The expressions suggested by Khare (1969) for ionization cross sections per unit energy range have been utilized to calculate the values of the mean energy expended in the production of an ion pair by a beam of fast electrons in molecular nitrogen and oxygen and atomic oxygen of uniform density. The values are practically constant for the energy of the incident electron greater than about 1 keV and are 15-20% higher than the experimental values.Keywords
