- Firstly , with the help of angular momentum coupling theory , the hamiltonian for multi - electron adorns is rewritten in terms of spherical tensors . the advantage of this form is that the radial , angular and spin parts are separated completely , which makes it easy to calculate the angular matrix elements by means of irreducible tensor . secondly , theoretical expressions of the relativistic corrections including the relativistic mass correction , the darwin correction terms , the electron - electron contact terms and the orbit - orbit interaction which contribute to the non - relativistic energy for two - electron atom are theoretically derived in the lsmlms scheme
具體內(nèi)容包括：首先，借助角動(dòng)量耦合理論，將多電子原子哈密頓算符中的自旋-自旋、自旋-其它軌道以及軌道-軌道相互作用全部改用球張量表示，這種球張量形式的優(yōu)點(diǎn)在于已將原子哈密頓算符中的徑向、角向和自旋部分完全分開(kāi)，從而便于計(jì)算矩陣元，而且角向矩陣元可以方便地利用不可約張量理論來(lái)進(jìn)行計(jì)算。 - In this thesis , based on racah method of two - electron atom and non - relativistic energy structure for helium - like atoms , the relativistic corrections and the fine structure of helium - like atoms , including the relativistic mass correction , the darwin correction terms , the electron - electron contact terms , the orbit - orbit interaction , the spin - orbit interaction , the spin - other - orbit interaction and the spin - spin interaction , are studied systemically using irreducible tensor . concretely , the main works of this thesis are as follows
