Proton-to-Alpha branching ratio in the ${}^{12}$C+${}^{12}$C fusion reaction at astrophysical energies

Ruojun Yang, Ruiqi Chen, Xiao Fang +4

The unique resonance features in the ${}^{12}$C+${}^{12}$C fusion reaction lead to significant fluctuations in the branching ratio $R_{p/\alpha }={\sigma }_p/{\sigma }_{\alpha }$, making it difficult to determine t…
