  • Title: Excitation of singly-ionized argon species in helium-matrix Grimm glow discharge plasmas II - Comparison between argon and neon.
    Author: Wagatsuma K, Hirokawa K.
    Journal: Anal Bioanal Chem; 1996 Jul; 355(7-8):876-7. PubMed ID: 15045285.
    Abstract:
    A considerable intensity enhancement of several Ar II lines assigned to the 3p(4)4p-3p(4)4s transition in a helium-argon Grimm glow discharge plasma has been previously reported and attributed to argon ions excited by metastable helium atoms. In this paper the behavior of Ne II lines assigned to the 2p(4)3p-2p(4)3s transition in a helium-neon plasma was investigated to obtain detailed information on the excitation of plasma gases in the helium-matrix plasmas. No Ne II lines with enhanced emission intensities have been found; on the contrary, the intensities of the doublet Ne II lines decreased in the helium-matrix plasma.
