Abstract
Oscillator strengths are given for transitions belonging to the a 5 S-z 5 P 0 and a 5 D-z 5 P 0 multiplets in Mn II. The data originate from beam-foil measurements of the z 5 P 1,2,3 0 level lifetimes and branching-ratio determinations. Theoretical f-values are also given for these transitions, the agreement between experiment and theory being satisfactory. Using the experimental gf-values obtained in this work and empirical solar models, the solar abundance of Mn has been determined to be log N Mn = 5.4 ± 0.2 (on the log N H = 12.00 scale).Keywords
