Abstract

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 (E_γ) and relative intensities (I_γ) 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 E_p = 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.

Nuclear Data Sheets for A = 110
2012, Nuclear Data Sheets
Evaluated nuclear structure and decay data for all nuclei within the A = 110 mass chain are presented. The experimental data are evaluated and best values for level and gamma-ray energies, quantum numbers, lifetimes, gamma-ray intensities, and other nuclear properties are recommended. Inconsistencies and discrepancies that exist in the literature are noted. This work supersedes the earlier evaluation by D. De Frenne and E. Jacobs (2000De11), published in Nuclear Data Sheets 89, 481 (2000).

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 J^π = 7⁺₁ ( $T_{12} = 4.9 h$ ) ground state and the J^π = 2⁺₁ ( $T_{12} = 69.1 min$ ) 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 $πg^{−1}_{92}$ , $ν g ̃_{72}$ multiplet was reproduced.
Nuclear structure of <sup>108</sup>In

γ-ray and γγ-coincidence spectra of the $^{108} Cd (p, n γ)^{108} In$ 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 E_p = 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.
