The dissociative recombination of HeNe+ ions with electrons: The partial rate constants for the formation of atoms in the 2p 53p configuration

Abstract

A simple experiment transparent for interpretation is presented in which afterglow of a discharge in helium with a small admixture of neon was studied. The intensities of the spectral lines of the Ne* atom at the stage of plasma decay were analyzed to find the conditions under which the dissociative recombination of heteronuclear ions HeNe+ + e → He + Ne* played a predominant role in the formation of part of the after-glow spectrum. The absolute values of partial coefficients responsible for the formation of excited neon atoms in the 2p 53p configuration were determined.
