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.
先前已有报道称，在氦 - 氩格里姆辉光放电等离子体中，归属于3p(4)4p - 3p(4)4s跃迁的几条氩离子（Ar II）谱线的强度有显著增强，这归因于亚稳态氦原子激发的氩离子。本文研究了在氦 - 氖等离子体中归属于2p(4)3p - 2p(4)3s跃迁的氖离子（Ne II）谱线的行为，以获取有关氦基质等离子体中气体激发的详细信息。未发现发射强度增强的Ne II谱线；相反，在氦基质等离子体中，Ne II双线的强度降低了。
