The unbound excited states of the most neutron-rich oxygen isotope, 24O (Z = 8, N = 16), have been investigated using the 24O(p,p′)24O*23O+n reaction at RIKEN, where a 63 MeV/neuclon secondary beam of 24O was produced in a Be production target by the projectile-like fragmentation of a 95 MeV/u 40Ar primary beam. The first 2+ excited state was observed in the invariant mass spectrum. This experiment will give us a deeper understanding of the new magic number at N = 16 in the neutron-rich oxygen isotopes.
