Abstract

The nucleus 110In has been studied via the reactions 107Ag(α, nγ)110In at 14.5 and 17 MeV, and 110Cd(p, nγ)110In at 7.5 MeV bombarding energy. Gamma-ray and γγ-coincidence measurements have been performed. Energies and relative intensities of 137 transitions in 110In have been determined. A more complete level scheme, containing 53 levels, has been deduced. From this new level scheme, the energy separation of the Jπ = 7+ 1 (T 1 2 = 4.9 h) ground state and the Jπ = 2+ 1 (T 1 2 = 69.1 min) isomer has been deduced to be 62.08±0.04 keV. The electron spectrum from the (α, nγ) reaction was measured with a superconducting magnetic spectrometer. Internal conversion coefficients of 30 transitions have been determined. Spins and parities have been deduced on the basis of the multipolarity of γ-transitions, and other arguments. Lifetime measurements were peformed by delayed coincidence and DSA methods. The energies and electromagnetic properties of the 110In states were calculated using the interacting boson-fermion-fermion/odd-odd truncated quadrupole phonon model. Several approximate proton-neutron multiplet states were identified and the unusual energy splitting of the πg-1 9 2, ν g ̃ 7 2 multiplet was reproduced.
