Résumé

The decays of ²¹⁴Po into ²¹⁰Pb and of ²¹²Po into ²⁰⁸Pb tagged by the previous decays from ²¹⁴Bi and ²¹²Bi have been studied inserting quartz vials inside the Counting Test Facility (CTF) at the underground laboratory in Gran Sasso (LNGS). We find that the mean lifetime of ²¹⁴Po is (236.00±0.42(stat)±0.15(syst)) μs and that of ²¹²Po is (425.1±0.9(stat)±1.2(syst)) ns. Our results are compatible with previous measurements, have a much better signal to background ratio, and reduce the overall uncertainties.
