Description

An unexpected strong interaction between normal deformed and triaxial strongly deformed levels at high spin, ∼32(ℎ/2π), is observed in 167Lu. This constitutes the first observation of accidental degeneracy, at such high spins, causing cross talk between levels in the normal deformed and in the second potential well in any known mass region. Furthermore, evidence of quasi-particle excitations highly competing with the wobbling excitation mode in a triaxial superdeformed well has been established in 167Lu
