【摘要】 以Breit-Pauli哈密顿的球张量形式为基础,借助不可约张量理论,对类铍原子1s~22snp组态能量的相对论修正(包括质量修正项、单体达尔文修正项、双体达尔文修正项和自旋-自旋接触相互作用修正项)进行了具体计算,计算结果与实验值数据符合的很好.更多还原

【Abstract】 Based on the tensor expression for the Breit-Pauli Hamiltonian,and with the aid of irreducible tensor theory,the relativistic corrections(including mass correction,one- and two-body Darwin correction and spin-spin contact interaction) to the non-relativistic energies of 1s~2 2sn p state energies in the Beryllium -like atoms have been calculated.And then the values of Relativistic corrections to the results are in good agreement with the experimental data.更多还原
