Abstract
The half-lives of the platinum isotopes Pt-189,Pt-191,Pt-197 and of the 4-d ay isomer in Pt-195m have been measured with high, precision using the phot oactivation technique. The gamma-ray activity was counted over several half -lives with a high-purity germanium detector. The measured half-lives are: T-1/2(Pt-189) = 12.1 +/- 1.5 h; T-1/2(Pt-191) = 2.862 +/- 0.007 d; T-1/2(Pt -197) = 19.96 +/- 0.05 h; T-1/2(Pt-195m) = 4.0104 +/- 0.0047 d.
