Abstract
Relativistic configuration interaction f values have been obtained for 264 transitions between the lowest 12 J = 9/2 and 22 J = 9/2° levels. Length and velocity gauges agree to 3.8% for the in-shell transitions, and 10.0% for the shell jump transitions. Two of the J = 9/2° levels are so nearly degenerate that it was necessary to introduce a semiempirical correction to produce the proper level ordering. Landé g values are calculated for all levels, and a more efficient way of adding magnetic Breit effects to the energy matrix is given.
