摘要: In this paper, we have studied the shapes coexistence in 180-190Hg isotopes. The SO(6) representation of eigenstates and a transitional Hamiltonian Interacting Boson Model are used to consider evolution from prolate oblate for systems with total boson number N = 9-12. Parameter free (up overall scale factors) predictions energy spectra quadrupole transition rates found be good agreement experimental counterparts. results control parameter offer combination spherical deformed these Hg isotopes also more deviation limit is observed when deformation decreased. Also, there some suggestion about expectation values operator which determined first state ground, beta gamma bounds model.
