 TITLE=/Structure of the unbound 11N nucleus by the (3He,6He)
        reaction/;
 PURPOSE=/This experiment was performed in order to confirm the
          energies and widths of the ground state and low-lying levels
          of the unbound 11N in the consideration of a possible halo
          structure in 11N./;
