A Model Analysis of Triaxial Deformation Dynamics in Oblate-Prolate n Shape Coexistence Pheno

From a viewpoint of oblate-prolate symmetry and its breaking, we adopt the nquadrupole collective Hamiltonian to study dynamics of triaxial deformation in nshape coexistence phenomena. It accommodates the axially symmetric rotor model, nthe gamma -unstable model, the rigid triaxial rotor model and an ideal nsituation for the oblate-prolate shape coexistence as particula..
