Interference effects in hyperfine induced $2s2s ^3P_0, ^3P_2 \to 2s^2 ^1S_0$ transitions of Be-like ions

Abstract

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.
