铬的电离势及类氦Cr^(22+)的E2和M1光谱跃迁的全相对论计算

Relativistic calculation of ionization energies for chromiumions CrⅠ to CrⅩⅩⅣ and magnetic dipole(M1) electronic quadruple(E2) parameters for He-like Cr^(22+)

基于相对论多组态自洽场方法 ,计算了CrⅠ至CrⅩⅩⅣ离子的基态能量和各价电离势 ,类氦Cr2 2 +离子的电四极矩和磁偶极矩光谱跃迁数据。计算中考虑了核的有限体积效应、Berit修正、QED修正和轨道极化效应。计算结果与文献的实验和计算值进行了比较。

The ionization potentials for ground state configuration of chromium ions from CrⅠ to CrⅩⅩⅣ have been calculated by using the relativistic Dirac Fock method with the corrections of finite muclear size, Breit, QED and orbital polarization. The results obtained are in good agreement with the experimental data available. Magnetic dipole(M1) and electronic quadruple(E2) parameters are presented for He like Cr 22+ .
