Abstract

Previous explanations for the resonance behavior of C12+C12 fusion at low energies were based on a nonresonant compound-nucleus background and an additional contribution from a series of resonances. This separation into "resonance" and "background" contributions of the cross section is artificial. We propose to explain this phenomenon through the impact on the cross section of the relatively large spacings and the narrow widths of Mg24 compound levels in the corresponding excitation-energy region.
