From detailed spectroscopy of Cd110 and Cd112 following the β+/electron-capture decay of In110,112 and the β- decay of Ag112, 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 Cd110, a γ band built on the shape-coexisting intruder configuration is suggested. For Cd112, the 2+ and 3+ intruder γ-band members are suggested, the 03+ band is extended to spin 4+, and the 04+ 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.
