MULTICONFIGURATION DIRAC-FOCK CALCULATIONS OF FINE-STRUCTURE ENERGIES FOR F-LIKE C1Ⅸ, ArⅩ, KⅪ AND CaⅫ

本文用相对论多组态Dirac-Fock方法计算了类氟离子ClⅨ,ArⅩ,KⅪ和CaⅫ的1s^22s^22p^5、1s^2s2p^6、1s^22s^22p^43s、1s^22s^2p^43p组态的精细结构能级和作为微扰的Breit修正、量子电动力学(Q,E,D)修正对能级的贡献,能级的计算值与实验值符合得很好。

In this paper, by reletivistic multiconfiguration Dirac-Fock code, we have calculated fine-structure energies for F-like ClⅨ,Arxxxxxxx, KⅪ and CaⅫ from Is22s22p5, 1s22s2p8, 1s22s22P43s, 1s22s22p43p configuration, and the contribution to level as for perturbative corrections of breit and quantum electrodynamic(QED). The level values of calculation and the known experimental values are in good agreement.
