Normal parity bands in 157Gd, 163Dy, and 169Tm are studied using the pseudo-SU(3) shell model. Energies and B (E2) transition strengths of states belonging to six low-lying, same-parity rotational bands in each nuclei are considered. The pseudo-SU(3) basis includes states with pseudospin 0 and 1, and 1/2 and 3/2, for even and odd nucleon numbers, respectively. States with pseudospin 1 and 3/2 must be included for a proper description of some excited bands.
