“…Previous studies have observed candidates for the three-phonon states in 110 Cd [8] 112 Cd [9], 114 Cd [10], 116 Cd [11] and 118 Cd [12]. However, this simple picture was shown to be at odds with the experimental data for the cases of 110,112,114 Cd by Garrett et al .…”

A study of the β + /EC decay of 110 In into levels of 110 Cd is combined with a reanalysis of data from a previous study of 110 Cd with the (n, n ′ γ) reaction with monoenergetic neutrons. The γγ coincidences from the 110 In decay leads to many new assignments of γ rays observed in the (n, n ′ γ) reaction, permitting the observation of weak low-energy transitions, and setting stringent upper limits on unobserved decay branches. The uncertainties on many of the lifetimes from the (n, n ′ γ) reaction are significantly reduced, and limits are established for the lifetimes of levels too long for a direct measurement. The absence of enhanced transitions between the previously assigned phonon states and the deformed intruder states strongly suggests that mixing between the configurations is generally weak, refuting the strong-mixing scenario as an explanation of the decay pattern of the excited 0 + states in 110 Cd. The decay pattern of the non-intruder states is suggestive of a γ-soft rotor, or O(6) nucleus, rather than a vibrational, or U (5) pattern. The existence of a 4p − 6h proton excitation in 110 Cd is also suggested.

“…Kawase et al in 1972 [9] first proposed a doublet of levels with spins 0 + and 3 − at 2079 keV. This was later confirmed [1][2][3]. An upper limit was determined by Corminboeuf et al, Ref [4], for the 1421.1-keV transition from the 2078.6-keV 0 + level.…”

“…Experiments with the (α, 2n) reaction by Kern et al [1], β decay measurements by Bertschy et al [2], light-ion induced reactions and decays by Kumpulainen et al [3], and an (n, n ′ γ) study by Corminboeuf et al [4] have identified multi-phonon states in the 110 Cd decay scheme indicating vibrational motion. The Cd nuclei have been considered as some of the best examples of near-harmonic vibrational behavior [5].…”

Abstract.A study of the 110 In β + /EC decay was performed at the TRIUMF Isotope Separator and Accelerator (ISAC) facility to probe the nuclear structure of 110 Cd. 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 110 Cd 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 110 Cd.
