Radiative transition probabilities have been calculated for the
magnetic dipole (M1) and electric quadrupole (E2) transitions
connecting the 63 metastable levels in the 
, 
and
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.
