Résumé :

The properties of the Be isotopes are studied by the deformed Hartree-Fock method with Skyrme interactions. It is shown for 11Be that the configuration where the last neutron occupies a Kπ= 1/2+ orbital is not the ground state but has a matter density distribution with a tail typical of a halo nucleus. Correlations are introduced in deformed mean-field wave functions by a restoration of rotational invariance. These correlations bring the amount of energy necessary to correct the deficiencies of pure mean-field wave functions.
