在准相对论框架下,以多电子原子精细结构哈密顿的球张量形式为基础,借助不可约张量和角动量耦合理论,导出类铍离子1s22snp(n=2-6)3P态精细结构(包括自旋-轨道相互作用、自旋-其它轨道相互作用和自旋-自旋相互作用)和精细结构参数的解析表达式,并利用我们所开发的程序,对各项进行了具体地计算,计算结果与文献符合地较好.

Theoretical calculation of the fine-structure energy and parameters for 1s22snp 3P (n=2-6,Z=5-8) state of Be-like ions

Within the quasi-relativistic framework, based on the tensor expression of the fine-structure Hamiltonian for many-electron atoms, and with the help of irreducible tensor theory and the angular momentum coupling theory, an analytic formula of the fine-structure energies (including spin-orbit interaction, spin-other-orbit interaction and the spin-spin interaction) of the 1s22snp(n=2-6) 3P State in Be-like ions have been derived. And then, by the virtue of the program code which compiled by us, we concretely calculated each term of the fine-structure. The results are in close agreement with the experimental data. Meanwhile, parameters of the fine-structure have been calculated further.
