摘要
利用全实加关联方法,以类锂等电子序列为研究对象,通过自旋-轨道相互作用和自旋-其它轨道相互作用算符的期待值计算了类锂离子等电子序列(Z=9~20)的高角动量1s2ng(n=5~9)激发态的精细结构劈裂.为了获得更精确的理论结果,在类氢近似下估算了高阶相对论修正和量子电动力学(QED)效应对精细结构的贡献,得到的结果与等电子序列规律符合的很好.
The fine structure splittings for 1s2ng( n = 5 ~ 9) states of the lithium-like systems from Z = 9 to 20 are calculated with the full core plus correlation method. These fine structure splittings are determined by the expectation values of spin-orbit and spin-other orbit interaction operators. In order to make the results more precious,the higher-order relativistic contribution and quantum-electrodynamics( QED) contribution are considered for the high angular momentum states of these ions. The results obtained agree with the regularity of the isoelectronic sequence.
