Abstract:
The goal of the present work is to produce transition probabilities
with very low uncertainties for a selected set of multiplets of MnI
and MnII. Multiplets are chosen based upon their suitability for
stellar abundance analysis. We report on new radiative lifetime
measurements for 22 levels of MnI from the e8D, z6P, z6D, z4F,
e8S, and e6S terms and six levels of MnII from the z5P and z7P
terms using time-resolved laser-induced fluorescence on a slow
atom/ion beam. New branching fractions for transitions from these
levels, measured using a Fourier-transform spectrometer, are reported.
