Rare-earth nuclei and the pseudo-SU(3) model
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, andgR factors of136Xe,138Ba, and204Hg are calculated in a truncation free environment and the results are compared with the experimental data and other theories.
