γ-ray and γγ-coincidence spectra of the 110Cd(p, nγ)110In reaction were measured with Ge(Li), Ge(LEPS), and Ge(HP) spectrometers at 6 MeV bombarding proton energy. Energies (Eγ) and relative intensities (Iγ) of 95 110In transitions (including 70 new ones) have been determined. The electron spectrum of the reaction was measured with a combined magnetic plus Si(Li) spectrometer at Ep = 6 MeV. Internal conversion coefficients of 41 transitions in 110In have been determined for the first time. The angular distribution of γ-rays was measured at 5.2, 5.6, and 6 MeV bombarding proton energies. A new, more complete level scheme of 110In has been deduced. On the basis of the internal conversion coefficients of transitions, Hauser-Feshbach analysis of (p, n) reaction cross sections, γ-ray angular distribution (and other) results unambiguous spin and parity assignments were made to 11 excited 110In levels. The energies of several 110In proton-neutron multiplets were calculated on the basis of the parabolic rule derived from the cluster-vibration model. The comparison of experimental and theoretical results provided identification of about 20 p-n multiplet states in 110In.
