VARIATIONAL MULTIPARTICLE-MULTIHOLE MIXING WITH THE D1S GOGNY FORCE.

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. [ABSTRACT FROM AUTHOR]
