Description
The 12C + 12C fusion reaction plays a key role in several astrophysical explosive phenomena. However, the cross section for the 12C + 12C fusion reaction at the relevant energy region is difficult to determine because of both experimmental limitations and strong resonant structures. We develop a reaction model that explicitly treat the C + C channel and Mg channel. The model reproduces the contrasting resonant structures and smooth energy dependences observed in the two systems. In the analysis, the experimentally observed upper limit behavior of 12C +13 C to 12C +12 C fusion cross section is employed as a practical empirical constraint.
