Infinitesimal spin tensor
無限小自轉張量 -
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
本文以雙電子原子結構的拉卡理論和類氦離子的非相對論原子結構的計算結果為基礎，利用不可約張量理論，較為系統地研究了類氦離子的相對論效應和精細結構，包括相對論質量修正、達爾文修正、電子與電子之間接觸相互作用、軌道-軌道相互作用、自旋-自旋相互作用、自旋-其它軌道相互作用以及自旋-軌道相互作用。 -

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
具體內容包括：首先，藉助角動量耦合理論，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點在於已將原子哈密頓算符中的徑向、角向和自旋部分完全分開，從而便於計算矩陣元，而且角向矩陣元可以方便地利用不可約張量理論來進行計算。
