类铍离子超精细诱导$2s2s ^3P_0, ^3P_2 \to 2s^2 ^1S_0$跃迁的干涉效应

摘要:

基于多组态Dirac-Fock方法和HFST软件包,利用grasp 2K计算了类铍离子的超精细诱导$2s2p ^3P_0, ^3P_2 \to 2s^2 ^1S_0$ E1跃迁几率.结果表明,低Z类铍离子的干扰对超精细猝灭速率有很大影响,特别是对$2s2p ^3P_0 \to 2s^2 ^1S_0$跃迁.特别地,在这两个跃迁中,原子序数$Z$的干涉效应的趋势不是单调的。对于$2s2p ^3P_0 \to 2s^2 ^1S_0$ E1跃迁,在Z=7附近出现最强的干涉效应;对于$2s2p ^3P_2 \to 2s^2 ^1S_0$ E1跃迁,在Z=9附近出现最强的干涉效应。

英文摘要:

The hyperfine induced $2s2p ^3P_0, ^3P_2 \to 2s^2 ^1S_0$ E1 transition probabilities of Be-like ions were calculated using grasp2K based on multi-configuration Dirac-Fock method and HFST packages. It was found that the hyperfine quenching rates are strongly affected by the interference for low-Z Be-like ions, especially for $2s2p ^3P_0 \to 2s^2 ^1S_0$ transition. In particular, the trends of interference effects with atomic number $Z$ in such two transitions are not monotone. The strongest interference effect occurs near Z=7 for $2s2p ^3P_0 \to 2s^2 ^1S_0$ E1 transition, and near Z=9 for $2s2p ^3P_2 \to 2s^2 ^1S_0$ E1 transition.
