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,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進(jìn)行計(jì)算。
In a word, a new method that theoretically calculates the relativistic corrections and the fine structure of the energy levels in two-electron atom, including the atomic hamiltonian expressed by spherical tensors, the calculation of the angular matrix elements and the summations over spin of the various interactions in the atomic hamiltonian, and the approximate calculation of the radial matrix elements, has been provided in this thesis 總之,本文為雙電子原子能級(jí)的相對(duì)論修正和精細(xì)結(jié)構(gòu)的理論計(jì)算提供了一種新的方法,包括原子哈密頓算符的球張量表示方法、原子哈密頓中各種相互作用項(xiàng)的角向矩陣元和自旋求和的計(jì)算方法,以及徑向矩陣元的近似計(jì)算方法
