Paper Abstract

This paper is devoted to studying the mechanism of super-fast relaxation of first Eu ion metastable states in discharge plasma in Eu-vapor-inert gas mixture. The threshold pressure of Ne for starting the first Eu ion quasi-continuous lasing at (lambda) equals1,0019 micrometers has been determined using two methods. Ratio of decay constants for de-excitation of Eu ion metastable state for He-Eu and Ne-Eu mixtures, which was close to the value (M+/-Ne)/ M+/-He))3/2 is congruent to 11 has been determined also. The obtained results show that relaxation of Eu+7D+/-j)0metastable states goes either during formation of(EuX)+* quasi molecule or during the recombination process. Structure of lower terms of the first Eu ion presented has two systems of 7 and 9 multiplet levels. Each system consists of the ground state and of resonance and metastable state groups. This system of levels corresponds to the agreed upon three-levels scheme of self-termination transition lasers.
