Status on ${}^{12}\mathrm{C}+{}^{12}\mathrm{C}$ fusion at deep subbarrier energies: impact of resonances on astrophysical $S^{\ast }$ factors

C. Beck, A. M. Mukhamedzhanov, X. Tang

Since the discovery of molecular resonances in ${}^{12}$C+${}^{12}$C in the early sixties a great deal of research work has been undertaken to study $\alpha$-clustering and resonant effects…
