Gamma rays following the decay of the $^{197 g}$ Hg and $^{197 m}$ Hg radionuclides were measured using chemically-purified sources and a planar HPGe detector. In the case of $^{197 m}$ Hg, precise values of 94.68 (9)% and 5.32 (9)% were confirmed for the IT and EC branches, respectively, the latter discovered to differ significantly from previously published data. The half-lives of $^{197 g}$ Hg and $^{197 m}$ Hg were also measured as 64.81 (24) h and 23.82 (4) h.
