Abstract
The nucleus Lu-163 has been populated through the fusion-evaporation reacti on La-139(Si-29,5n)Lu-163 with a beam energy of 152 MeV. The electromagneti c properties of several connecting transitions between two presumably triax ial, strongly deformed (TSD) bands have been studied. Evidence is presented for the assignment of the excited TSD band as a wobbling mode built on the yrast TSD band, based on comparisons to new calculations in which an align ed particle is coupled to a strongly deformed triaxial rotor. The wobbling mode is uniquely related to triaxiality in nuclei.
