类锂离子Ni^(25+)和Zn^(27+) 2p态的精细结构分裂

Fine structure splitting of lithiumlike ions Ni^(25+) and Zn^(27+) 2p states

应用MCDF(multi-configuration Dirac Fock)方法计算了类锂离子Ni25+和Zn27+2p态的精细结构分裂,在计算中考虑了横光子相互作用、真空极化修正和自能修正对精细结构的影响。计算Ni25+和Zn27+离子2p态的精细结构分裂分别为177 512.60 cm-1和239 100.50 cm-1,与实验值相比误差分别为16.5 cm-1和13.7 cm-1。横光子相互作用和自能修正的贡献较大,而真空极化修正只有很小的贡献。

Fine structure splitting of lithiumlike ions Ni^25＋ and Zn^27 ＋ 2/0 states was calculated by using MCDF （ multi- configuration Dirac Fock） method. And the effects of transverse photon interaction, vacuum polarization correction and self-energy correction were considered in the calculation. Theoretical results of fine structure splitting of 2p states for Ni^25＋ and Zn^27＋ ions are 177 512. 60 cm^-1 and 239 100. 50 cm^-1 , lower than the experimental values 16. 5 cm^-1 and 13.7 cm^-1 respectively. The transverse photon interaction and self-energy correction are more important to the splitting while the vacuum polarization correction is ignorable relatively.
