Abstract
We develop an RPA approach based on rotating potentials as an extension of the rotating shell model of nuclear high-spin states. The RPA formalism is applied to the positive-parity yrast spectrum of 164Er. Properties at high spin of the pairing potentials and of the γ-vibrational bands are analyzed as functions of the rotational frequency. The result of calculation indicates an onset in the s-band of instability toward triaxial deformation.Keywords
