Relativistic Configuration Interaction Fe III 3d J=4 → 3d4p J=3,4,5 f-values

Electric Dipole f -values have been obtained between the seven 3d J=4 even states, and all the 3d 4p J=3,4,5 odd states. Seventy two of these exceed 0.01 and are published here. The average agreement between the length and velocity gauges is 1.8%. Due to the small size of the f -values, non-orthogonality effects may be significant in shell jump cases, as we have here. Many of the odd levels are so nearly degenerate that the introduction of small semi-empirical corrections is necessary. We compare favorably (17% on average) to the most modern of the three available semi-empirical data sets.
