Abstract

We have studied the α-decays of ²¹⁴Po into ²¹⁰Pb and of ²¹²Po into ²⁰⁸Pb tagged by the coincidence with the preceding β-decays from ²¹⁴Bi and ²¹²Bi, respectively. The ²²²Rn, ²³²Th, and ²²⁰Rn sources used were sealed inside quartz vials and inserted in the Counting Test Facility at the underground Gran Sasso National Laboratory in Italy. 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, obtained from data with signal-to-background ratio larger than 1000, reduce the overall uncertainties and are compatible with previous measurements.
