Resonant behaviour in the interaction of the 12C + 12C system at energies above the coulomb barrier

Abstract

Resonances in the 12C + 12C interaction at E cm = 7.45, 8.45, 8.85 and 9.25 MeV corresponding to excitation energies in 24Mg of 21.4, 22.4, 22.8 and 23.2 MeV respectively are reported. These resonances are seen in the proton and alpha exit channels. No resonances in 12C + 12C were reported previously in this energy region, where earlier calculations predicted a group around E cm = 7.6 MeV.
