Variational multiparticle-multihole mixing with the D1S Gogny force
Résumé
Applying a variational multiparticle-multihole mixing method whose purpose is to include correlations beyond mean field in an unified way without particle number and Pauli violations, we investigate ground state properties of $^22O$ nucleus, in the case of pairing-type correlations. The same interaction is used for the mean field and the residual part of the hamiltonian, namely, the density-dependent D1S Gogny force
