Structure Of Excited K=0(+) Bands In Er-168

Using the Gamma-Ray- Induced Dopplerbroadening (GRID) technique, lifetimes of states in the gamma- and K=O-3(+) band in Er-168 were determined. The resulting absolute B(E2)-values are compared with theoretical models describing Er-168 within the framework of the Interacting Boson Model (IBM) and the Triaxial Projected Shell Model (TPSM). Special emphasis is put on a reinterpretation of the level scheme in terms of the new Partial Dynamical Symmetry (PDS) approach.
