The excited states of ${}_{}{}^{116}{}_{}{}^{}\mathrm{Sn}$ were studied by means of the decays of the 15.8-min, $3^{+}$ ${}_{}{}^{116}{}_{}{}^{}\mathrm{Sb}$ ground state, and the 60.3-min, $8^{\mathrm{-}}$ ${}_{}{}^{116}{}_{}{}^{}\mathrm{Sb}$ isomer. Over 50 γ rays were observed; these were incorporated into a level scheme consisting of 32 excited states. Except for one new level proposed at 3.986 MeV, the current study fully supports an exhaustive study of levels in ${}_{}{}^{116}{}_{}{}^{}\mathrm{Sn}$ reported earlier. The previous study was an attempt to develop a nearly ‘‘complete’’ level scheme of ${}_{}{}^{116}{}_{}{}^{}\mathrm{Sn}$ up to an excitation energy of 4.3 MeV.
