The Cd-112 laboratory: An extension. E0 strengths, multiphonon states and coupled vibrations

The structure of Cd-122 was investigated using the Cd-111(n(th),gamma) and Pd-110(alpha,2n) reactions. High resolution crystal and magnetic spectrometers as well as different Compton-suppressed spectrometers were used. The results were combined with published data resulting in a complete level scheme over a large range of spins and excitation energies. The interpretation of the data was performed in the framework of the interacting boson model (IBM). A special effort was put in the interpretation of E0 data and an attempt was made to identify multiphonon and 2(1)(+) x 3(1)(-) states.
