Distributions of populations of atomic levels in quasi-stationary argon plasma

Abstract

Populations of argon atomic levels have been calculated within the meta-equilibrium model of a two-temperature quasi-stationary plasma. A specific feature of meta-equilibrium two-temperature plasma of inert gases is “broken” population level distributions of atoms making it possible to explain the results of spectroscopic studies of the arc discharge in argon at atmospheric pressure (the experiment by V.N. Kolesnikov).
