Abstract:
    Radiative transition probabilities have been calculated for the
    magnetic dipole (M1) and electric quadrupole (E2) transitions
    connecting the 47 metastable energy levels in the 3d^8^, 3d^7^ 4s and
    3d^6^ 4s^2^ configurations in Co II. The most important configuration
    interaction (CI) and relativistic effects have been taken into account
    in the computations carried out with the help of the relativistic
    Hartree-Fock (HFR) method combined with a semi-empirical optimization
    of the radial parameters.
