Excitation transfer in the plasma of a barrier discharge in a krypton-xenon mixture

Processes of excitation transfer in the plasma of a barrier discharge in a krypton-xenon mixture are studied. A kinetic diagram of energy transfer is proposed, and a system of coupled kinetic equations describing the dynamics of processes in the plasma of a barrier discharge of mixtures in pure xeno n as well as in a krypton-xenon mixture is composed and solved. The effect of excitation transfer on the population distribution over vibrational leve ls of krypton excimers excited by a barrier discharge in a krypton-xenon mi xture is studied. The deviation from the equilibrium distribution over vibr ational levels is found. It can be interpreted as an indication of the acti vation of the mechanism of depopulation of the lowest vibrational levels of excimer states of krypton. (C) 2001 MAIK "Nauka/Interperiodica".
