    "abstract": "We measure the lifetime of the 8s level on a magneto-optically trapped sample\nof ^{210}Fr atoms with time-correlated single-photon counting. The 7P_{1/2}\nstate serves as the resonant intermediate level for two-photon excitation of\nthe 8s level completed with a 1300 nm laser. Analysis of the fluorescence decay\nthrough the the 7P_{3/2} level gives 53.30 +- 0.44 ns for the 8s level\nlifetime.",
