Description
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 e^8^D, z^6^P, z^6^D, z^4^F, e^8^S, and e^6^S terms and six levels of MnII from the z^5^P and z^7^P 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.
