The {gamma}-ray and internal conversion electron spectra of the {sup 116}Sn({ital p},{ital n}{gamma}){sup 116}Sb reaction have been measured at {ital E}{sub {ital p}}=6.3, 6.7, and 7.2 MeV bombarding energies with Ge(HP), Ge(HP,LEPS) {gamma} and superconducting magnetic lens plus Si(Li) electron spectrometers. The energies and relative intensities of 90 {sup 116}Sb {gamma} rays, as well as internal conversion coefficients of 21 {sup 116}Sb transitions have been determined. Angular distribution data have been obtained for 37 {gamma} rays. A more complete level scheme of {sup 116}Sb has been deduced, which contains 38 levels below 1500 keV excitation energy. Multipolarities of transitions and {gamma}-ray branching ratios have been deduced. Calculated Hauser-Feshbach ({ital p},{ital n}) cross sections have been compared with experimental values. Level spins and parities have been determined on the basis of the Hauser-Feshbach analysis, internal conversion coefficients, and {gamma}-ray angular distribution data. The energies of several {sup 116}Sb proton-neutron multiplets have been calculated using the parabolic rule. Members of different multiplets have been identified.
