Abstract
We use two-photon resonant excitation and time-correlated single-photon counting techniques on a sample of 210Fr atoms confined and cooled in a magneto-optical trap to measure the lifetime of the 9s excited level. Direct measurement of the decay through the 7P3/2 level at 851 nm yields a lifetime of 107.53±0.80 ns .
