Abstract

Radiative lifetimes have been reported for 32 odd-parity levels of neutral lanthanum using a time-resolved laser-induced fluorescence technique in an atomic beam produced by laser ablation. The energies of these levels are in the range of 23,874 to 37,982 cm 1 . Among the measured results, to the best of our knowledge, 23 lifetimes are reported for the first time. These lifetime values obtained in this paper, generally with uncertainties less than ± 10 % , are in the range of 7.3 to 247 ns . These results are in good agreement with previously reported data within the experimental errors.
