电离度效应对重类氢离子跃迁概率的影响

The Influence of the Ionicity Effect on the Transition Probabilities of Heavy Hydrogenlike Ions

摘要: 在高电离态类氢离子的新势函数模型下 ,电子近核区域运动的相对论效应、有限核效应、量子电动力学 (QED)等效应已被电离度效应所取代 .利用包含电离度效应的类氢离子波函数 ,系统研究了电离度效应对重类氢离子电偶极跃迁概率的影响 .发现电离度效应使类氢He+ 9至Pm+ 60 离子的跃迁概率相对增加 3 .5 5 %—1 0 .3 8% .这有利于实验研究者估价自己测量到的原子或离子状态的正确性. In this paper, by means of using the wavefunction taking th e ionicity effect into account of hydrogenlike ions, the influence of the ionicity effect on the transition probabilities of heavy hydrogenlike ions is systematic ally studied under a new model of potential function of hydrogenlike ions. It is found that the relative increase of the transition problbilities is from 3.55 t o 10.38 percent for the ions from Ne +9 to Pm +60 because of the ionic ity effect.
