摘　　要：以相对论修正哈密顿(包括质量修正、单体和双体达尔文修正、自旋-自旋接触相互作用)的张量形式为基础,借助不可约张量理论导出了类氩体系基态能量的相对论修正的解析表达式.在斯莱特表象中完成了所有的角向积分和自旋求和计算,能量的相对论修正式用径向矩阵元的线性组合来表示.对类氩体系基态能量的相对论修正值进行了具体计算,修正后基态能量与实验值的相对误差小于0.0459%.Based on the tensor expression for the Breit-Pauli Hamiltonian and with the aid of irreducible tensor theo-ry, the matrix elements in sets of Slater functions of the relativistic correction operators, which include mass correction term, one-and two-body Darwin correction terms, spin-spin contact interaction term and orbit-orbit interaction term, have been derived explicitly and presented by radial matrix elements.The theory is applied to the calculations of ground state energies of Agron-like atoms and all the relative differences are smaller than 0.046%.
