作为核高自旋态的旋转壳模型的推广，我们发展了一种基于旋转势的RPA方法。将RPA形式应用于164Er的正宇称yrast谱。分析了对偶势和γ振动带在高自旋时的性质随转动频率的变化。计算结果表明，该失稳带开始向三轴变形发展。
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 of164Er. 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 thes-band of instability toward triaxial deformation.
