Reactions of excited atoms of neon in neon-helium afterglows. II. Kinetic model

Abstract

For pt.I see ibid., vol.18, p.2793 (1985). A kinetic model describing the relaxation of excited-atom populations of neon in dense neon-helium afterglows is presented and applied to experimental data. The major de-excitation processes were found to involve collisions with neutrals and other excited atoms. Comparison of computer-generated and observed decay profiles showed that electron-ion recombination represented an afterglow source of the excited-atom population. The self-consistency of recently reported rate coefficients and constants by Akoshile et al (1985) was confirmed.
