Abstract
We show that the rotation axis of a triaxial nucleus may flip from the intermediate axis () to the smallest axis () due to the polarization by an aligned pair. The example we discuss is the triaxial nucleus where the isoscalar pair aligns to in and flips the rotation from to . Calculations are performed in the spherical shell model as well as in the cranked Nilsson-Strutinsky model, supporting the suggested scenario. The role of the interaction in forming the pair is discussed in both models.
