摘　　要：以双电子原子精细结构哈密顿的球张量形式和二价原子的非相对论性能级结构理论为基础,借助不可约张量理论,导出了氦原子(n1sn2p)组态精细结构能级的解析表达式,在这一过程中,完成了所有的角向积分和自旋求和计算,其结果用若干个径向矩阵元形式来表示.Based on the tensor expression of the fine-structure Hamiltonian for two-electron atoms and the non-relativistic energy structure theory for atoms with two valence electrons, and with the help of irreducible tensor theory, analytical expressions of the fine structure for n 1 sn2p configuration of Helium-like atoms have been derived. All the angular integrations and spin summations involved in the problem have been carried out explicitly, the energy is expressed finally as a sum of some radial matrix elements.
