Abstract

A study of the ¹¹⁰In β⁺/EC decay was performed at the TRIUMF Isotope Separator and Accelerator (ISAC) facility to probe the nuclear structure of ¹¹⁰Cd. The data were collected in scaled-down γ-ray singles, γ - γ coincidence, and γ-electron coincidence mode. The data were sorted and a random-background subtracted γ - γ matrix was created containing a total of 850 million events. We expanded the level scheme of ¹¹⁰Cd significantly by identifying 75 levels under 3.8 MeV, including 12 new ones, and increased the number of previously observed transitions from these levels to 273. The γ-ray branching intensities have been extracted through an analysis of the coincidence intensities. The branching ratios were combined with a reanalysis of lifetimes measurements obtained in an (n, n'γ) reaction with monoenergetic neutrons for the calculation of B(E2) values and these results have lead to the proposal of a γ-soft rotor, or O(6) nucleus, rather than a vibrational, or U(5) pattern for the nature of the low-lying, low-spin levels in ¹¹⁰Cd.
