摘要：
The half-lives of the platinum isotopes 189,191,197Pt and of the 4-day isomer in 195mPt have been measured with high precision using the photoactivation technique. The γ-ray activity was counted over several half-lives with a high-purity germanium detector. The measured half-lives are: T1/2(189Pt) = 12.1 ± 1.5 h; T1/2(191Pt) = 2.862 ± 0.007 d; T1/2(197Pt) = 19.96 ± 0.05 h; T1/2(195mPt) = 4.0104 ± 0.0047 d.
