The γ-ray spectrum of the 114Cd(p, nγ)114In reaction was measured with Ge(Li) and Ge(HP) spectrometers at 4.8, 5.3, and 7.0 MeV bombarding proton energies. The energies (Eγ) and relative intensities (Iγ) of more than 170 γ-ray transitions in 114In have been determined. The electron spectrum of the reaction was measured with a combined magnetic plus Si(Li) spectrometer. Internal conversion coefficients of 38 transitions in 114In were determined for the first time. The level scheme of 114In, γ-ray branching ratios, multipolarity of transitions, level parity and spin values have been deduced. The energies of several 114In 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 classification of about 18 multiplet states in 114In. The experimental level scheme has also been compared with former theoretical calculations.
