The γ-ray and internal conversion electron spectra of the Sn116(p,nγ)116Sb reaction have been measured at Ep=6.3, 6.7, and 7.2 MeV bombarding energies with Ge(HP), Ge(HP,LEPS) γ and superconducting magnetic lens plus Si(Li) electron spectrometers. The energies and relative intensities of 90 Sb116 γ rays, as well as internal conversion coefficients of 21 Sb116 transitions have been determined. Angular distribution data have been obtained for 37 γ rays. A more complete level scheme of Sb116 has been deduced, which contains 38 levels below 1500 keV excitation energy. Multipolarities of transitions and γ-ray branching ratios have been deduced. Calculated Hauser-Feshbach (p,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 γ-ray angular distribution data. The energies of several Sb116 proton-neutron multiplets have been calculated using the parabolic rule. Members of different multiplets have been identified.
