Non-yrast split parity-doublet spectra in odd-mass nuclei — •Michael Strecker1, Nikolay Minkov2 und Horst Lenske1 — 1Institut für Theoretische Physik, Universität Gießen — 2Institute of Nuclear Research and Nuclear Energy, Sofia, Bulgaria
We extend the coherent quadrupole and octupole model to describe non-yrast split parity-doublet bands in odd-A nuclei. It is shown that the model describes both the yrast and non-yrast quasi-parity doublet spectra and the related B(E1) and B(E2) transition rates in various odd-A nuclei from the rare-earth to the actinide region. As in case of even-even nuclei we make use of an analytically derived formula for the energies. The model parameters are adjusted in order to obtain the best description of the experiment. The observed Coriolis decoupling effects are taken into account phenomenologically. Results are compared to recent spectroscopic data.
