Abstract:
We report electric quadrupole and magnetic dipole transitions among
the levels belonging to 3d64s, 3d7 and 3d54s2 configurations
of Fe II in a large scale configuration interaction (CI) calculation.
The CIV3 code developed by Hibbert and coworkers is used to determine
configuration interaction wave functions for these levels: for the
optimisation of two different sets of orbitals based on alternative
choices of the 3d function, for creating and diagonalising the
Hamiltonian matrices and finally for calculating transition
probabilities.
Description:
Table 5:
The energy levels of configurations 3d64s, 3d7 and 3d54s2
listed in increasing energy order. We give the usual spectroscopic
notation for each level, including their LSJ values, and also their
energy levels in cm-1 above the ground level. Excited level
energies in the form xxx.000 are calculated, the others are from the
NIST tabulations
Tables 6-8:
The A-values of both E2 and M1 transitions, and their sum, for
transitions involving only the levels listed by NIST. The indices of
the levels refer to those given in Table 5.
Table 9:
The A-values of both E2 and M1 transitions, and their sum, for
transitions involving those levels NOT listed by NIST. In addition the
transitions involving level 99 are included here since they were not
calculated in the determinations which led to Tables 6-8. The indices
of the levels refer to those given in Table 5. The order of the
transitions is in increasing energy order of the lower level, and for
a particular lower level, in increasing energy order of the upper
level, as in Table 6.
