Abstract

The decays of Po-214 into Pb-210 and of Po-212 into Pb-208 tagged by the previous decays from Bi-214 and Bi-212 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 (214)po is (236.00 +/- 0.42(stat) +/- 0.15(syst)) us and that of Po-212 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. (C) 2014 Elsevier Ltd. All rights reserved.
