Nuclear structure of 110In

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