The non-thermal plasma in a helium hollow cathode discharge is analysed by means of experiments and theory. The population densities of excited levels are calculated by a system of equations, including the different processes which occur in the plasma. A detailed examination of the mechanism of exitation and deexcitation follows. From this, a refined method is developed for the determination of the electron temperature by the intensity of a helium line.

Abstract The number densities of excited hydrogen atoms in a non-thermal plasma have been calculated on the basis of a coupled system of rate equations (25 levels) in which one accounts for electron-atom and atom-atom collisions. The calculated population densities depend strongly on the neutral particle density na when ne/na≪1. When the electron temperature, Te, is different from the gas temperature, Tg , the number densities of the excited levels are determined by Tg rather than by Te. This is important in connection with the quantitative spectroscopy of plasmas.
