Interband B(E2) transition strengths in odd-mass heavy deformed nuclei -: art. no. 034306

Interband B(E2) transition strengths between different normal parity bands in Dy-163 and Er-165 are described using the pseudo-SU(3) model. The Hamiltonian includes Nilsson single-particle energies, quadrupole-quadrupole and pairing interactions with fixed, parametrized strengths. and three extra rotor terms used to fine tune the energy spectra. In addition to interband transitions, the energy spectra and the ground state intraband B(E2) strengths are reported. The results show the pseudo-SU(3) shell model to be a powerful microscopic theory for a description of the normal parity sector in heavy deformed odd-A nuclei.
