The ${}^{12}C{+}^{12}C$ reaction is one of the most important reactions in the evolution of massive stars. The cross-section and the astrophysical S factor were calculated using the potential of AW95 and the new optimized potential. The new optimized potential in reproducing the fusion cross section and astrophysical S factor is very successful at low energies, also the hindrance and maximum in S factor is visible in this same energy range and is in good agreement with the experimental results. But at higher energies, the results obtained using the AW95 potential are in better agreement with the experimental results. However, it is appropriate to use this new potential to reproduce the barrier phenomenon and the experimental results at low energies, which are more important in astrophysics. The S-factor, obtained in the coupled channel calculation for the ${}^{12}C{+}^{12}C$ reaction, had a maximum value at energy near 3.6 MeV.

这 ${}^{12}C{+}^{12}C$反应是大质量恒星演化过程中最重要的反应之一。横截面和天体物理 S 因子是使用 AW95 的潜力和新的优化潜力计算的。新的优化潜力在低能量下非常成功地再现聚变截面和天体物理 S 因子，并且 S 因子的阻碍和最大值在相同的能量范围内是可见的，并且与实验结果非常吻合。但是在更高的能量下，使用 AW95 电位获得的结果与实验结果更加吻合。然而，利用这种新势能在低能量下再现势垒现象和实验结果是合适的，这在天体物理学中更为重要。在耦合通道计算中获得的 S 因子${}^{12}C{+}^{12}C$ 反应，在能量接近 3.6 MeV 时具有最大值。
