Description
Some consequences of the BCS mechanism in nuclei are studied in the effective sigma-model formalism. With adaptations to finite systems, the O(6)-O(5) symmetry breaking chain in the interacting boson model is reproduced reasonably well both in magnitude and form. The same holds to a lesser degree for the U(3)-O(3) chain. Supersymmetry aspects of the model are also discussed. (orig.)
