BALMERα,β, γ EMISSION IN COLLISIONS OF H_1^+,H_2^+, H_3^+ WITH He,Ne,Ar

实验利用TN-1710光学多道分析系统(OMA),对H_1^+,H_2^+,H_3^+和He,Ne,Ar碰撞过程中产生的巴耳末系H_α,H_β,H_γ发射进行了测量,入射离子H_1^+,H_2^+,H_3^+的实验室能量范围为50—150keV。本文给出H_α,H_β,H_γ谱线的发射截面。实验结果表明:在H_3^+离子和He,Ne,Ar原子碰撞过程中,H_α的发射截面分别比H_2^+,H_1^+离子和He,Ne,Ar原子碰撞过程的大,也就是说,电子俘获几率,前者比后者大,而H_1^+离子和He,Ne,Ar原子碰撞过程的最小。

Balmer α, β, γ emission have been measured in collisions between H_1^+, H2+, H_3^+ and He, Ne, Ar respectively, by using TN-1710 Optical Multichannel Analysis System (OMA), in laboratray energy range of 50-150 keV. The emission cross sections of H_α, H_β, H_γ lines are given in this paper. The experimental results demonstrate that the emission cross sections of H_α,H_β,H_γ in H_3^+ + He, Ne, Ar collision systems are greater than that in H_1^+ , H_2^+ + He, Ne, Ar respectively, it means the probabilities of one electron capture into excited states are larger in the former than that in the latters from the targets.
