Ar^(17+)离子能级和跃迁性质的相对论理论计算

Relativistic Calculation of the Energy Levels and Transition Properties in Ar^(17+) ion

基于多组态Dirac-Fock理论方法,计算了高离化态Ar17+离子1s-4d精细结构能级以及各能级间的跃迁几率。为研究相对论效应和QED效应对高离化态离子能级的影响,分别给出了横向光子交换相互作用、真空极化、质量位移和自能的能量修正项。结果表明包括这些高阶项后,计算结果与文献的结果符合的非常好。

The energies and transition probabilities for the electric dipole transition between the ground state ls and the excited states of nI （n=2-4,1=s, p, d） configurations of Ar17＋ have been calculated with the help of the Muhi-configuration Dirac-Fock method. To study the influence of the relativistic and the QED effects on the energy levels of the highly charged ions, the energy corrections of the transverse photon exchange interaction, vacuum polarization, mass term and self-energy have been given respectively. The results show that the calculation results of this paper are in good accordance with the results of the literature.
