Résumé : A candidate of a neutron-halo nucleus, 31Ne, contains a single neutron in the pf shell. Within Glauber and eikonal models, we analyze reactions used to study 31Ne. We show in a 30Ne+n model that the magnitudes of the total reaction and above all of the one-neutron removal cross sections of 31Ne on 12C and 208Pb targets strongly depend on the orbital angular momentum of the valence neutron, thereby providing efficient ways to determine the structure of 31Ne ground state. We also show that elastic-breakup observables exhibit a strong dependence upon the orbital of the valence neutron. © 2010 World Scientific Publishing Company.
