Abstract:
Radiative transition probabilities have been calculated for the
magnetic dipole (M1) and electric quadrupole (E2) transitions
connecting the 63 metastable levels in the 3d64s, 3d7 and 3d54s2
configurations in Fe II. The most important configuration interaction
(CI) and relativistic effects have been taken into account in the
computations carried out with the help of two independent computer
programs, SUPERSTRUCTURE (SST) and RELATIVISTIC HARTREE-FOCK (HFR).
The results obtained in the present work are compared with previous
theoretical studies and with some astrophysical observations. The new
data presented here are probably the most reliable to date.
