Abstract

Radiative lifetimes for 63 odd-parity energy levels of neutral lanthanum, in the range 13 , 260 30 , 965 cm 1 , have been measured using time-resolved laser-induced fluorescence technique in a supersonic free-jet produced by laser vaporization of lanthanum metal. To the best of our knowledge, lifetimes for 45 levels are reported for the first time. The present lifetimes, with a few exceptions, are found to be in good agreement with the previously reported data. Lifetime values reported in this work fall in the range 9.5 to 313 ns and are accurate to ± 10 % . The levels belong to the 5 d 6 s 6 p , 4 f 6 s 2 , 6 s 2 6 p , 5 d 2 6 p , and 4 f 5 d 6 s electronic configurations.
