    "abstract": "The multiconfiguration Dirac-Hartree-Fock (MCDHF) model has been employed to\ncalculate the transition rates between the nine lowest levels of radium. The\ndominant rates were then used to evaluate the radiative lifetimes. The decay of\nthe metastable $ 7s7p ^3 P_0 $ state through 2-photon E1M1 and hyperfine\ninduced channels is also studied.",
