Abstract

We show that the rotation axis of a triaxial nucleus may flip from the intermediate axis (γ=30) to the smallest axis (γ=+30) due to the polarization by an aligned T=0np pair. The example we discuss is the triaxial N=Z nucleus Ge64 where the isoscalar π(g9/2)ν(g9/2) pair aligns to iπ=9+ in As66 and flips the rotation from γ30 to γ30. 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 np interaction in forming the np pair is discussed in both models.
