Abstract

The wobbling mode is uniquely related to rotation of a triaxial body. The LuHf isotopes with N 94 provides a possible region of nuclei with pronounced triaxiality. We have investigated 163Lu through the fusion-evaporation reaction 139La(29Si,5n)163Lu with a beam energy of 152 MeV. The eletromagnetic properties of several connecting transitions between two presumably Triaxial, SuperDeformed (TSD) bands have been studied. New particle-rotor calculations in which an aligned i13=2 proton is coupled to a "wobbling" core are presented and evidence for the assignment of the excited TSD band as a wobbling mode built on the yrast TSD band in 163Lu is given.

N2 - The wobbling mode is uniquely related to rotation of a triaxial body. The LuHf isotopes with N 94 provides a possible region of nuclei with pronounced triaxiality. We have investigated 163Lu through the fusion-evaporation reaction 139La(29Si,5n)163Lu with a beam energy of 152 MeV. The eletromagnetic properties of several connecting transitions between two presumably Triaxial, SuperDeformed (TSD) bands have been studied. New particle-rotor calculations in which an aligned i13=2 proton is coupled to a "wobbling" core are presented and evidence for the assignment of the excited TSD band as a wobbling mode built on the yrast TSD band in 163Lu is given.
