Gamma-ray transitions in ${}_{}{}^{205}{}_{}{}^{}\mathrm{Hg}$ have been observed in the ${}_{}{}^{204}{}_{}{}^{}\mathrm{Hg}$(t,d${)}^{205}$Hg reaction. A partial level scheme is obtained. Delayed gamma rays exhibiting ${\tau }_m$=(1.59±0.06)×${10}^{\mathrm{-}3}$ s are observed; the identification with the decay of the $i_{13/2}$ neutron hole state is suggested.
