摘要：

We have observed a resonance in neutron-fragment coincidence measurements that is presumably the first excited state of O-23 at 2.8(1) MeV excitation energy which decays into the ground state of O-22. This interpretation is consistent with theory. The reaction mechanism supports the assignment of the observed state as the 5/2(+) hole state. This assignment and the recently observed 3/2(+) particle state advance the understanding of O-23.
