Abstract
We present transition energies, probabilities and branching ratios for the electric dipole allowed (E1) and forbidden (M1, E2, M2) lines of the 3s(2)3 p(4), 3s3p(5) and 3s(2)3p(3)3d configurations of Fe XI. Large-scale multico nfiguration Dirac-Fock wavefunctions are applied to include the effects of relativity, correlation and rearrangement of the electron density consisten tly within the same (computational) model. From the transition probabilitie s, lifetimes of the 46 lowest-lying excited levels are derived, and the pro spects for experimental verification are discussed. An M2 transition is ide ntified in the solar extreme ultraviolet spectrum.
