Abstract: | An extended version of the pseudo-SU(3) model is used to describe low-energy positive-parity states of three rare-earth nuclei in a full proton-neutron formalism. Along with other residual interactions, the Hamiltonian includes the pairing which induces mixing between different representations of SU(3). Excitation energies, B(E2) values, B(M1) values, quadrupole moments, andg R factors of136Xe,138Ba, and204Hg are calculated in a truncation free environment and the results are compared with the experimental data and other theories. |
