Abstract
The cascade Hanle-effect technique has been described in detail. It has been used to measure the radiative lifetimes of several excited S states in heavy alkali metal atoms. We obtained the following measurements (in nanoseconds): γ(K, 6 2S½) = 68 ± 9, γ(Rb, 7 2S½) = 91 ± 11, γ(Cs, 8 2S½) = 96 ± 14, and γ(Cs, 9 2S½) = 231 ± 35.Keywords
