Model fits were made to the cumulative distribution of all known levels (with spins J≤10) in ${}_{}{}^{116}{}_{}{}^{}\mathrm{Sn}$ below an excitation energy of 4.1 MeV identified in a variety of experiments, and simultaneously to the density of J=0 and J=1 resonances inferred from neutron capture and total cross-section measurements in ${}_{}{}^{115}{}_{}{}^{}\mathrm{Sn}$+n. Neither the back-shifted Fermi-gas model nor the constant-temperature model provides a satisfactory fit over the entire energy range. The generalized superfluid model, with a level-density parameter and a spin-cutoff factor that are both energy dependent, does give a good fit, and the resulting best-fit parameter values are consistent with those found in other applications of this model.
