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