 TITLE=/Experimental evidence of core modification in the near
        drip-line nucleus 23O/;
 PURPOSE=/IRecent studies of N=15,N,O,F isotopes shows an abrupt rise in
          interaction cross section.In this letter, we investigate the
          cause for this through the simultanious longitudinal momentum
          distribution measurements of one- and two-neutron removal
          fragments of 23O with a new direct TOF technique./;
