Abstract

New measurements of radiative lifetimes of four 3d<SUP>6</SUP>5s levelsin 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 oftheoretical calculations. The lines are of particular interest in the modeling of HLyalpha pumped fluorescence of Fe II in astrophysical plasmas.
