Abstract

Natural radiative lifetimes of 79 odd-parity highly excited levels of neutral samarium in the energy range from 18,985.70 to 34 , 189.56 cm 1 have been measured by time-resolved laser-induced fluorescence technique in an atomic beam produced by laser ablation. The lifetime results obtained in this paper are in the range from 8.3 to 786.6 ns. When these results are compared with the previous measurements, a good agreement is achieved. This work will be useful to extend the set of oscillator strengths available in Sm I.
