Abstract

The lifetimes of the first excited states of the elements Na, K, Rb, and Cs were measured using the phase-shift method described by Brewer <i>et al.</i> [Rev. Sci. Instr. 33, 1450 (1962)]. The data were taken over a wide range of vapor densities to allow the effects of radiation entrapment and of scattered exciting light to be taken into account. The following values were obtained: Na 3<i>p</i><sup>2</sup><i>P</i> 16.1±0.3 nsec, K 4<i>p</i><sup>2</sup><i>P</i> 27.8±0.5 nsec, Rb 5<i>p</i><sup>2</sup><i>P</i><sub>3/2</sub> 27.0±0.5 nsec, and Cs 6<i>p</i><sup>2</sup><i>P</i><sub>3/2</sub> 30.5±0.7 nsec.
