摘要
Gamma rays following the decay of the 197gHg and 197mHg radionuclides were measured using chemically-purified sources and a planar HPGe detector. In the case of 197mHg, precise values of 94.68 (9)% and 5.32 (9)% were determined for the IT and EC branches, respectively, the latter found to differ significantly from previously published data. The half-lives of 197gHg and 197mHg were also measured as 64.81 (24) h and 23.82 (4) h.
