摘要: 采用全相对论量子力学GRASP2程序、广义平均能级EAL模型,在核的有限体积效应、Breit和QED效应的高阶扰动基础上,考虑到原子实的极化,系统地计算了高剥离类钾离子组态3p63d(Z=22~42)磁偶极矩M1光谱跃迁的能级间隔、跃迁几率和振子强度,计算中选取4个非相对论输入组态3p63d1,3p64s1,3p54s3d,3p54s2,将计算结果和最近文献的实验值及理论计算值进行比较,结果表明,考虑原子实极化效应后,计算的精细能级结构间隔与实验数据之间的系统误差基本消除.

关键词: 高剥离态, 能级间隔, 跃迁几率, 振子强度

Abstract: A fully reIativistic multiconfiguration Dirac-Fock method with Breit and QED corrections is used to caIcuIate the magnetic dipoIe 3p63d2D5/2-2D3/2Z=22~42)transition energy level separations,transition probabilities and oscillator strengths for the K-like ions. In calculation,significant core polarization effects,Breit and OED corrections are considered. The results are in agreement with recent experiments. A substantial part discrepancy disappears in the 2D5/2-2D3/2 separations when core excitation channels are taken into account. There are no transition probability and oscillator strength resuIts in the isoelectronic seguence until now.

Key words: highly stripped ions, energy level intervals, transition probabilities, oscillator strengths
