• 論文の詳細を見る

• From the viewpoint of oblate-prolate symmetry and its breaking, we adopt the quadrupole collective Hamiltonian to study the dynamics of triaxial deformation in shape coexistence phenomena. It accommodates the axially symmetric rotor model, the γ-unstable model, the rigid triaxial rotor model, and an ideal situation for the oblate-prolate shape coexistence as particular cases. Numerical solutions of this model yield a number of interesting suggestions. (1) The relative energy of the excited 0^+ state can be a signature of the potential shape along the γ direction. (2) Specific E2 transition probabilities are sensitive to the breaking of the oblate-prolate symmetry. (3) Nuclear rotation may induce the localization of collective wave functions in the (β, γ) deformation space.
