The level scheme of {sup 116}Sn has been studied by combining the results of {sup 115}Sn({ital n},{gamma}){sup 116}Sn and {sup 116}Sn({ital n},{ital n}{prime}{gamma}){sup 116}Sn experiments. Both experiments were performed using isotopically enriched samples and Ge {gamma}-ray detectors. Based on the thresholds of {gamma}-ray excitation functions measured for the {sup 116}Sn({ital n},{ital n}{prime}{gamma}) reaction and the precise {gamma}-ray energies from the capture reaction, 100 levels were observed below 4.3 MeV excitation energy. Approximately half of these were not known previously. Forty-eight of these levels have unique or tentative spin-parity assignments, and for ten more the spin has been restricted to a single value. The spin-parity for most other levels below 4.3 MeV excitation has been restricted to a few values. These spin-parity assignments and limitations were derived mainly from ({ital n},{ital n}{prime}{gamma}) angular distribution measurements, together with additional information obtained from the cross section magnitudes in both experiments.
