Casten, R F

A simple approach to the IBA is described, which exploits the consistent Q-formalism to describe both symmetries and transition regions with a minimum of parameters. Some results with this approach are discussed and compared with the data for deformed and transitional nuclei. Following this introduction, a new region of O(6) symmetry is presented and compared with the Pt region with which it is found to share many similarities. Discrepancies with the strict limiting symmetry are described in terms of symmetry breaking via a small triaxial potential. 28 refs., 15 figs.
