| 摘 要： | Using the multi-configuration Dirac-Fock self-consistent field method and the relativistic configuration interaction method with quantum-electrodynamics corrections performed by the GRASP code, we calculate the fine-structure energy levels of the ground-state configuration （1s^22s^22p^3） of the nitrogen isoelectronic sequence, according to the L-S coupling scheme with atomic number Z up to 22. Based on the calculated results, we elucidate the mechanism of the orderings of fine-structure energy levels of 2^ D3/2,5/2 and 2^P1/2,3/2 respectively, i.e. for 2^D3/2,5/2 orderings, the competition between the spin-orbit interactions and the Breit interactions; for 2^P1/2,3/2 orderings, the electron correlations, especially the electron correlations owing to the 2p^5 configuration interactions.

| Abstract: | Using the multi-configuration Dirac--Fock self-consistent field method and the relativistic configuration interaction method with quantum-electrodynamicscorrections performed by the GRASP code, we calculate the fine-structure energy levels of the ground-state configuration (1s22s22p3) of the nitrogen isoelectronic sequence, according to the L-S coupling scheme with atomic number Z up to 22. Based on the calculated results, we elucidate the mechanism of the orderings of fine-structure energy levels of 2D3/2,5/2 and2P1/2,3/2 respectively, i.e. for 2D3/2,5/2 orderings, the competition between the spin--orbit interactions and the Breit interactions; for 2P1/2,3/2 orderings, the electron correlations, especially the electron correlations owing to the2p5 configuration interactions. |
