Shape evolution of 172Hg under varying neutron pairing strengths.

Caption

Potential energy surfaces on the (q2, η) plane show the transition of the ground-state minimum from triaxial to oblate as the neutron pairing strength Gν (MeV) increases. The nucleus is nearly γ-unstable, with shallow energy valleys and several shape isomers, including prolate, triaxial, and oblate minima. Increasing pairing strength reduces the depth of these local minima, eventually eliminating the triaxial isomer.
