TLDR
In this article, the relativistic Hartree-Fock (HFR) method combined with a semi-empirical optimization of the radial parameters was used to calculate the transition probabilities for the magnetic dipole and electric quadrupole transitions connecting the 47 metastable energy levels in the 3d 8, 3d 7 4s and 3d 6 4s 2 configurations in Co II.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 parametersread more
