| Abstract: | The General Collective Model (GCM) is revised and applied to the chain of182–196Hg- and96–108Ru-isotopes. Calculated energy spectra, absolute B(E2) values and Quadrupole moments are presented and compared to experiment. For many of these nuclei a coexistence of spherical and triaxial shapes was found. Additionally we investigated the shape transition within the Ru-chain from prolate (96Ru) over spherical (98Ru) to triaxial (A ≧100). The results are compared to microscopic and IBA calculations. |
