摘　　要：利用对角和法则,导出了氮原子和类氮离子(Z=7-12)基态(电子组态为1s22s2p3)非相对论能量的解析表达式.在考虑了电子间交换相互作用以及内外壳层电子的不同屏蔽效应的基础上,利用变分原理计算了能量值,计算结果与实验数据符合得较好,误差均小于0.3%.Based on the diagonal sum rule, the non-relativistic energy levels of ground state, corresponding to the configurations of the nitrogen-like atoms from Z = 7 to 12 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 calculated results are in good agreement with the experimental data, and the difference between the calculated result and the experimental data is less than 0.3 %.
