Pulsed population inversion in recombination of positive metal ions with negative ions of sulfur, selenium, and tellurium

Abstract

Ion-ion recombination of positive ions of 14 metals with negative ions of sulfur, selenium, and tellurium is considered. The energy levels of metal atoms predominantly populated in the process of ion-ion recombination are estimated. The possibility of creating the population inversion in the afterglow of a pulsed discharge on some atomic transitions is discussed along with realization of noncoherent sources of radiation.
