Abstract：
A Nilsson mean–field plus extended pairing interaction Hamiltonian with many–pair interaction terms is summarized. The investigation shows that one–and two–body interactions continue to dominate the dynamics for relatively small values of the pairing strength. As the strength of the pairing interaction grows, however,higher many–body interaction terms grow in importance. As an example, numerical fits to even–odd mass differences in the ^154—171YB isotopes shows that the new model is applicable to well–deformed nuclei.
