A pseudo shell SU(3) model description of normal parity bands in Tb-159 is
presented. The Hamiltonian includes spherical Nilsson single-particle energ
ies, the quadrupole-quadrupole and pairing interactions, as well as three r
otor terms. A systematic parametrization is introduced, accompanied by a de
tailed discussion of the effect each term in the Hamiltonian has on the ene
rgy spectrum. Yrast and excited band wavefunctions are analyzed together wi
th their B(E2) values. (C) 2000 Elsevier Science B.V. All rights reserved.
