$Ab~Initio~f$ values for Fe II $J=9/2 \rightarrow 9/2^o$ transitions

Relativistic configuration interaction $f$ values have been obtained for 264 transitions between the lowest 12 $J=9/2$ and the 22 $J=9/2^o$ levels. Length and velocity gauges agree to 3.8\% for in-shell transitions and 10.0\% for shell jump transitions. Two $J=9/2^o$ levels are so nearly degenerate that it was necessary to introduce a semi-empirical correction to produce the correct level ordering. The results are in overall good agreement with the semi-empirical results of Kurucz \footnote{R. L. Kurucz, http://kurucz.harvard.edu/atoms/2601/} and Raassen \footnote{A. J. J. Raasen, ftp://ftp.wins.uva.nl/pub/orth/iron/FeII.E1 (1999)}. An efficient method of including magnetic Breit effects in the energy matrix is presented.
