摘要： Excitation energies, transition wavelengths and probabilities of the 2p6, 2p5 3l,2s 2p6 3l (l = 0; 1; 2) states along the Ne-like isoelectronic sequence from Z =21?92 have been calculated by using the Multi-conˉguration Dirac-Fock package GRASP92 and a newly developing radiative transition program REOS99. In the calculations, the correlation and relaxation e?ects are included systematically.Based on the calculations, all possible energy crossings among the level groups with the same parity and total angle momentum have been presented. It is found that there are strong conˉguration interactions in some particular Z regions with energy-crossings, and which can cause a dramatic change of the related transition probabilities.

关键词: MCDF method, Energy crossing, conˉguration interaction, transition prob-abilities
