Abstract

Electric dipole f-values have been obtained between the seven 3d 6 J = 4 even states, and all the 3d54p 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 favourably (19% on average) to the most modern of the three available semi-empirical data sets. © 2007 IOP Publishing Ltd.
