Abstract
The empirical spectra and decay rates in Cd are shown to be consistent with a vibrational interpretation for low-lying normal states, coexisting with a single deformed -soft band of intruder states. The observed deviations from this paradigm show up in particular non-yrast states, which are properly described by a Hamiltonian with U(5) partial dynamical symmetry. The latter is characterized by a good (broken) symmetry in most (in selected) normal states, weakly coupled to intruder states.
