Abstract
The self-consistent quasiparticle-phonon coupling equations are solved for deformed superfluid nuclei in the rare earth region. Parameters are chosen to agree with previous calculations, and the solutions for -, -, and octupole-vibrational states are compared to experiments and to previous descriptions of both even- and oddmass nuclei. The importance of exclusion principle violations in the rare earth region is noted as well as the interference of pairing and quadrupole correlations in the even nuclei with . An "intruder" state is predicted in the Eu and Tb isotopes. The splitting of the states in and is derived from higher-order contributions to the self-energy.
