MFMF-dependent hyperfine induced transition rates in an external magnetic field for Be-like 47Ti18+

Hyperfine induced 2s2pP03→2s2S01 transition rates in an external magnetic field for Be-like 47Ti were calculated based on the multiconfiguration Dirac–Fock method. It was found that the transition probability is dependent on the magnetic quantum number MFMF of the excited state, even in the weak field. The present investigation clarifies that the difference of the hyperfine induced transition rate of Be-like Ti ions between experiment [Schippers, et al., Phys. Rev. Lett. 98 (2007) 033001(4)] and theory does not result from the influence of external magnetic field.
