Frequency of collisions between electrons and gas and vapor atoms and molecules

A resonant method based on the phenomenon of electron cyclotron resonance is used to determine the frequency of collisions between electrons and He, Ar atoms and H₂S, SO₂, H₂O, and CsCl molecules. Electron distribution over energy is measured under experimental conditions and the mean electron energy determined therefrom. Existing techniques of collision frequency measurement and calculation are discussed. Experimental dependences of reduced collision frequency on mean electron energy are obtained and the parameter E/N is compared to values presented in the literature.
