Abstract:
    Radiative transition probabilities have been calculated for states
    within the 3d6 configuration of Fe III. Magnetic dipole (M1) and
    electric quadrupole (E2) transition probabilities have been obtained
    using average energies, electrostatic and spin-orbit integrals
    adjusted so as to fit the observed energy levels. The most important
    configuration interaction (CI) and relativistic effects were included
    explicitly in the calculations, using the relativistic Hartree-Fock
    (HFR) method due to Cowan. The present work represents a refinement
    of previous monoconfigurational calculations of transition
    probabilities for forbidden lines of astrophysical interest in Fe III.

Note (1): Predicted wavelengths are deduced from the observed energy levels
           (Ekberg 1993). They are given in air above 200 nm and in vacuum
           below 200 nm.
Note (2): c calculated HFR wavelength.
Note (3): * Cancellation effects present.
