摘要
基于MCDF方法系统地计算了Z=20~83范围内24个类铍离子的1s22s2p3P0,1态的精细结构,得到了与其它理论和实验符合很好的结果.在此基础上,进一步计算了超精细结构对角及非对角常数,并分析了不同电子关联效应和Breit相互作用对它们的影响.
The Multi-configuration Dirac-Fock method is employed to compute the fine structure energies of the 1s^2 2s2p^3 P0,1 levels of Be-like ions. The present calculations are in good agreement with existing theoretical and experimental results. On the basis of this, the hyperfine interaction diagonal and off-diagonal constants of the 1s^2 2s2p^3 P0,1 levels are calculated. The effects of electron correlation and Breit interaction on these properties are investigated.
