氦原子自旋-其它轨道相互作用精细结构参数的理论计算
Theoretical calculation of the fine structure parameter for spin-other-orbit interaction in helium
摘要
Abstract
Based on the tensor expression of the fine structure Hamiltonian and the non-relativistic energy structure theory for helium, and by virtue of irreducible tensor theory, an analytical method for calculating the fine structure parameter for spin-other-orbit interaction in helium-like atoms is established. All the angular integrations and spin summations involved in the problem have been carried out explicitly, the parameter is expressed finally as a sum of some radial integrations. Approximate evaluation for these radial integrations in the (1s2p)3P state of helium is outlined, in which the hydrogen-like radial functions are employed. It is found that in the fine structure of helium, the spin-other-orbit interaction and the pure spin-orbit interaction act in the opposite directions, and it is the former that plays the most important role, which determines the splitting order of the fine structure.关键词
