摘要
采用拉卡基函数并借助角动量耦合理论 ,导出了三价原子非相对论性哈密顿的矩阵元的一般表达式 ,完成了所有的角向积分和自旋求和计算 ,结果用 3j、6j和 9j符号表示 ,径向积分则表示为Slater Condon参数。用相关结果对 (n1p) 2 (n2 p)组态的谱项结构进行了分析。
Non-relativistic energy structure for atoms with three valence electrons has been studied using Racah method. General expressions for the matrix elements of the atomic Hamiltonian have been derived. The orbital integrations and the summations over spin are completed with the help of angular momentum coupling theory and are presented by 3j, 6j and 9j symbols, while the radial integrations are expressed by Slater-Condon parameters. The results are applied to the case of (n_1p)~2(n_2p) configuration for which all the ten term energies are presented by means of the derived matrix elements.
