Hyperfine induced transitions in He-like, Be-like and Mg-like ions

Abstract

Hyperfine quenching rates for 1s2s 1S0 → 1s2 1S0 M1 transition of He-like ions, 2s2p 3P0 → 3P2 → 2s2 1S0 E1 transition of Be-like ions and 3s3p 3P0 → 3s2 S0 E1 transition of Mg-like ions have been calculated from relativistic configuration interaction wavefunctions including the frequency independent Breit interaction and QED effects. The present study not only supply accurate theoretical values for developing atomic clocks, diagnosing low-density plasma, probing nuclear properties, exploring weak interaction beyond standard model, but also to analyze some characteristics in hyperfine induced transitions.
