Abstract
A novel laser-induced fluorescence technique was used to measure lifetimes of 14 3d5 (4G) 4p and 3d5(4P) 4p levels in the Mn+ ion. Branching fractions for electric dipole transitions from these levels were measured with a vacuum ultraviolet Fourier transform spectrometer using a hollow-cathode lamp and a Penning discharge source. Base on these new measurements, absolute electric dipole transition rates for about 170 spectral lines in the ultraviolet and vacuum ultraviolet were determined. The uncertainty of the transition rates is less than 5% for the strong transitions.Citation
