Multiple shape coexistence in 110,112 Cd
From detailed spectroscopy of Cd-110 and Cd-112 following the +/electron-capture decay of In-110,In-112 and the − decay of Ag-112, very weak decay branches from nonyrast states are observed. The transition rates determined from the measured branching ratios and level lifetimes obtained with the Dopp...

| Sumario: | From detailed spectroscopy of Cd-110 and Cd-112 following the +/electron-capture decay of In-110,In-112 and the − decay of Ag-112, very weak decay branches from nonyrast states are observed. The transition rates determined from the measured branching ratios and level lifetimes obtained with the Doppler-shift attenuation method following inelastic neutron scattering reveal collective enhancements that are suggestive of a series of rotational bands. In Cd-110, a band built on the shape-coexisting intruder configuration is suggested. For Cd-112, the 2(+) and 3(+) intruder -band members are suggested, the 0(3)(+) band is extended to spin 4(+), and the 0(4)(+) band is identified. The results are interpreted using beyond-mean-field calculations employing the symmetry conserving configuration mixing method with the Gogny D1S energy density functional and with the suggestion that the Cd isotopes exhibit multiple shape coexistence. |
