Shell model description of normal parity bands in odd-mass heavy deformed nuclei - art. no. 031301

The low-energy spectra and B(E2) electromagnetic transition strengths of (E U)-E-159, Tb-159, and Dy-159 are described using the pseudo SU(3) model. No rmal parity bands are built as linear combinations of SU(3) states, which a re the direct product of SU(3) proton and neutron states with pseudospin ze ro (for even number of nucleons) and pseudospin 1/2 (for odd number of nucl eons). Each of the many-particle states has a well-defined particle number and total angular momentum. The Hamiltonian includes spherical Nilsson sing le-particle energies, the quadrupole-quadrupole and pairing interactions, a s well as three rotor terms which are diagonal in the SU(3) basis. The pseu do SU(3) model is shown to be a powerful tool to describe odd-mass heavy de formed nuclei.
