Model fits were made to the cumulative distribution of all known levels (with spins [ital J][le]10) in [sup 116]Sn below an excitation energy of 4.1 MeV identified in a variety of experiments, and simultaneously to the density of [ital J]=0 and [ital J]=1 resonances inferred from neutron capture and total cross-section measurements in [sup 115]Sn+[ital 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.
