The FERRUM project:: Experimental f-values for 4p-5s transitions in FeII

New measurements of radiative lifetimes of four 3d(6)5s levels in Fe II at about 10 eV are presented along with absolute oscillator strengths for twenty 4p-5s transitions involving the four levels. The experimental measurements are compared with two different sets of theoretical calculations. The lines are of particular interest in the modeling of HLy alpha pumped fluorescence of Fe II in astrophysical plasmas.
