Electric dipole $f$ values for Fe II $J=9/2\rightarrow 11/2^o$ transitions
POSTER
Abstract
Relativistic configuration-interaction $f$ values have been obtained for all transitions between the lowest 17 $J=9/2$ and the lowest 27 $J=11/2^o$ levels. The 35 $f$ values $>$0.01 have an average gauge agreement of 3.6\% and generally agree well with the semi-empirical results of Raassen \footnote{A. J. J. Raassen, {\sf ftp://ftp.wins.uva.nl/pub/orth/iron/FeII.E1} (1999).}. The near degeneracy of many of the odd levels requires the introduction of small semi-empirical energy shifts \footnote{D. R. Beck, Phys. Scr. {\bf 71}, 447 (2005).}. A systematic way of estimating radial convergence is discussed.
