洞态氩离子的退激发及末电离态离子分布的理论研究

Cascade decays and final charge-state distribution of hollow argon ions

在描述洞原子(或离子)退激发过程只考虑单俄歇跃迁和辐射跃迁的辐射-单俄歇级联退激发模型的基础上,进一步考虑了双俄歇跃迁的贡献,发展了辐射-单俄歇-双俄歇级联退激发模型.据此模型研究了Ar+(1s-1)(1s洞态氩离子)和Ar+(2s-1)(2s洞态氩离子)的退激发过程及末电离态离子的分布,获得了与实验相符的结果.

On the basis of a previous model of radiative-Auger-cascade for calculation of final-charge-state distributions of hollow ions, a new model of radiative-Auger-double Auger-cascade has been constructed by including double Auger process, and was applied to study the final-charge-state distribution in the production of Ar^＋ （Is^-1） （argon ion with an initial ls hole） and Ar^＋ （2s^-1） （argon ion with an initial 2s hole）. Comparing with the previous calculations and experiments, the present results show excellent agreement.
