Oscillator strengths for ionized iron and manganese.
Abstract
Summary. The observed strengths of interstellar absorption lines of Fe ii and Mn ii in the spectra of oc Vir, P Cen, Sco, and Oph along with laboratory f values of some of these lines between 2343 and 2606 A have been used to determine curves of growth for these ions and the f-values of 10 lines of Fe ii and 3 lines of Mn ii between 1055 and 1261 A. The Fe and Mn abundances are derived. Key words: oscillator strengths - interstellar absorption lines
