Triaxial Strongly Deformed bands in ^163Tm
Abstract
A ``thin'' target experiment and a DSAM lifetime measurement were carried out with the reaction ^130Te(^37Cl,4n) using Gammasphere at LBNL and at ANL, respectively. It has been confirmed that the two new bands in ^163Tm, interpreted as TSD bands based on particle-hole excitations, are associated with a larger deformation than the yrast sequences. The measured quadrupole transition moments will be compared with those of neighboring nuclei. Further, TAC calculations will be presented. They provide a natural explanation for the presence of wobbling bands in the Lu isotopes and the absence of such bands in all neighboring Tm, Hf and Ta nuclei.
