Abstract

The hyperfine induced 4f145s5p 3P0,2o  4f145s2 1S04f^{14}5s5p~^3\mathrm{P}^o_{0,2}~-~4f^{14}5s^2~^1\mathrm{S}_0 transition probabilities for highly charged Sm-like ions are calculated in the framework of the multi-configuration Dirac-Hartree-Fock method. Electron correlation, the Breit interaction and quantum electrodynamical (QED) effects are taken into account. For ions ranging from Z=79Z=79 to Z=94Z=94, 4f145s5p 3P0o4f^{14}5s5p~^3\mathrm{P}^o_{0} is the first excited state, and the hyperfine induced transition is an dominant decay channel. For the 4f145s5p 3P2o4f^{14}5s5p~^3\mathrm{P}^o_{2} state, the hyperfine induced transition (HIT) rates of Sm-like ions with Z=8294Z=82-94 are reported as well as the magnetic dipole (M1) 3P2o  3P1o^3\mathrm{P}^o_2 ~-~ ^3\mathrm{P}^o_1, the electric quadrupole (E2) 3P2o  3P0,1o^3\mathrm{P}^o_2 ~-~ ^3\mathrm{P}^o_{0,1}, and the magnetic quadrupole (M2) 3P2o  1S0^3\mathrm{P}^o_2 ~-~ ^1\mathrm{S}_0 transition probabilities. It is found that M1 transition from the 4f145s5p 3P2o4f^{14}5s5p~^3\mathrm{P}^o_2 state is the most important decay channel in this range on Z82Z \ge 82.
