Abstract
It is pointed out that the triaxial bands in 138-140Nd and in the Lu/Er nuclei can be understood from the same shell structure effects. Two of the bands in 138Nd, interpreted as signature partners, exhibit a crossing at high spins with a signature splitting which is strongly reduced above the crossing. This behavior is unique among the yrast and close-to-yrast configurations, revealing the mechanism which induces a change of the rotation axis from short to intermediate in the triaxially deformed nucleus.
