Nuclear structure of 108In

γ-ray and γγ-coincidence spectra of the 108Cd(p,nγ)108In reaction were measured with Ge(Li), Ge(HP,LEPS), and Ge(HP) spectrometers for different bombarding proton energies between 6.8 and 9.0 MeV. The energies and relative intensities of 142 108In transitions (including 131 new ones) have been determined. The electron spectrum of the reaction was measured with a superconducting magnetic lens plus Si(Li) detector and independently with combined intermediate-image magnetic plus Si(Li) spectrometers at Ep=7.2 MeV. Internal conversion coefficients of 19 transitions in 108In have been determined. The angular distributions of γ-rays were measured at 6.8 and 7.2 MeV bombarding proton energies. A more complete level scheme of 108In has been deduced which contains 54 levels below 1630 keV excitation energy. On the basis of the internal conversion coefficients of transitions, Hauser-Feshbach analysis of (p, n) reaction cross sections, γ-ray angular distributions and other arguments, spin and parity assignments were made to 24 excited 108In levels. Lifetime measurements were performed by a delayed coincidence method. The energies of several 108In proton-neutron multiplets were calculated on the basis of the parabolic rule derived from the cluster-vibration model. Interacting boson-fermion-fermion/odd-odd truncated quadrupole phonon model calculations were also performed. The calculations gave a reasonable description of the energy-level spectrum and electromagnetic properties of 108In. (orig.)
