Abstract
We present transition energies, probabilities and branching ratios for the electric dipole allowed (E1) and forbidden (M1, E2, M2) lines of the 3s23p4, 3s3p5 and 3s23p33d configurations of Fe xi. Large-scale multiconfiguration Dirac-Fock wavefunctions are applied to include the effects of relativity, correlation and rearrangement of the electron density consistently within the same (computational) model. From the transition probabilities, lifetimes of the 46 lowest-lying excited levels are derived, and the prospects for experimental verification are discussed. An M2 transition is identified in the solar extreme ultraviolet spectrum.
