The kinetics of excited atoms and optical radiation under conditions of wave mechanism of breakdown in inert gases

Based on an analysis of the results of integrated experimental and theoretical investigations, modern concepts are described of the kinetics of excited atoms and optical radiation under conditions of the wave mechanism of breakdown in inert gases. Primary attention is given to optical investigations in the gas pressure range from 1 to 1000 torr with voltage pulse amplitudes of up to 60 kV. The effect of fast electrons, formed at the ionization wave front, on the intense and polarization profiles of spontaneous spectral lines is treated. The role of the processes involving molecular ions in the formation of the optical properties of plasma.developed by wave breakdown is discussed. The possibility is studied of using such discharges for pumping recombination gas lasers.
