A mean‐field plus extended pairing interaction Hamiltonian that includes multi‐pair scattering terms is proposed for describing well‐deformed nuclei. Eigenvalues of the model are easily obtained. The investigation shows that even through the extended pairing includes many‐body terms, the 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, the higher many‐body interaction terms grow in importance. A numerical study of even‐odd mass differences in the 154–171Yb isotopes demonstrates the applicability of the theory.
