Abstract
An infinite-dimensional algebraic approach is introduced to derive exact pa rticle-number conserving solutions of the nuclear mean-field plus orbit-dep endent pairing Hamiltonian. As an example, exact solutions of a model Hamil tonian for de-shell nuclei are compared with shell-model and equal strength pairing calculations for O18-26 isotopes.
