Abstract
Picosecond laser-induced fluorescence spectroscopy and a pulsed hollow cathode discharge are applied to measure 66 radiative lifetimes of Ta II, Ti II, Ce II, Zr II, Zr I, and Fe I levels. In the present investigation systematic influences like polarization and magnetic field effects, radiation trapping, quenching and the duration of the exciting laser pulse are considered in the data analysis. The selective laser excitation of the levels under investigation is performed by a frequency-stabilized distributed feedback dye laser system and the fluorescence is recorded by photon counting technique to ensure best sensitivity and time-resolution. The typical pulse duration is 100 ps and the spectral bandwidth 0.006 nm. The absolute accuracy of the data is 3 to 6%.
