VIBRATIONAL STATES OF ODD-A DEFORMED NUCLEI IN THE RARE EARTH REGION

Energies, wave functions of the quadrupole and hexadecapole states, B(Eλ) and B(M1) values are calculated within the quasiparticle-phonon nuclear model in a number of well-deformed even-even nuclei in the rare earth region. Reasonably good overall agreement with available experimental data is obtained. Specific properties of the Kπ = 0+ and two-gamma vibrational states are discussed. The distributions of the M1 strength is studied. It is shown that the M1 strength is more strongly fragmented in Er isotopes compared to Gd and Dy isotopes. The fragmentation of one- and two-phonon states is investigated. The fragmentation of one-phonon states strongly affects the Eλ and M1 strength distribution at energies above 2.5–3.0 MeV. The wave functions in the energy range 2–4 MeV contain specific nuclear structure information and these states cannot be treated as chaotic.

The Rare Earth

The residual p-n interaction in doubly odd deformed nuclei is examined in the framework of the unified model. Extensive experimental information about the Gallagher-Moszkowski splitting energies and Newby shifts in the rare-earth and actinide regions is used to deduce empirical parameters of the residual p-n interaction. Delta interaction and Gaussian-shape radial potential are assumed, Empirical p-n parameters are discussed and compared with previously deduced parameters. For the first time, errors in the parameters are estimated and special attention is paid to parameter significance.
