Meaning of S-D dominance

The dominance of S and D pairs in the description of deformed nuclei is one of the facts that provided sustenance to the interacting boson approximation. In Dukelsky and Pittel [Phys. Rev. Lett. 86, 4791 (2001)], using an exactly solvable model with a repulsive pairing interaction between bosons, it...
