Gas temperature in an alkali plasma
Abstract
A method is proposed for determining the gas temperature in a weakly ionized alkali vapor plasma from the measured ratio of the concentrations of the atoms and diatomic molecules of the same element. Criteria of the applicability of the method are obtained through a quantitative analysis of an equation of the balance of the number of dimers including possible processes of their formation and disintegration. The rate constants of three-particle atom-atom recombination in potassium, rubidium, and cesium vapors, required for the above analysis, are determined experimentally.
