【Abstract】 Based on the diagonal sum rule,the non-relativistic energy levels of the ground state,corresponding to the configurations of the natrium-like atoms from 11 to 14 is derived analytically.The exchange interaction between the inner shell and outer shell electrons and the dissimilar screening parameters for the different shells are considered.Then the energy levels have been calculated by variational method.The results are in good agreement with experimental data,and the difference between the calculated result and the experimental data is less than 0.45%.更多还原
