Resonance atEc.m.=12.8MeV in theC12+O16system

Abstract
An intermediate-type resonance of width Γc.m.=130±25 keV has been observed in the excitation functions of the n, p, d, and α-particle exit channels at Ec.m.=12.77 MeV in the C12 + O16 reaction. The energy of the resonance as well as its probable spin J=8 are in good agreement with the predictions obtained from the semiclassical expression for the grazing orbit.
