The ¹²C + ¹²C fusion reaction plays a significant role in the later phases of stellar evolution. For a better understanding of the evolution involved, one must understand the corresponding fusion‐fission dynamics and reaction characteristics. In the present analysis, we have studied the fusion cross‐section along with the S‐factor for this reaction using the well‐known M3Y and recently developed R3Y nucleon‐nucleon (NN) potential along with the relativistic mean‐field densities in double‐folding approach. The density distributions and the microscopic R3Y NN potential are calculated using the NL3^* parameter set. The ℓ‐ summed Wong model is employed to investigate the fusion cross‐section, with ℓ_max‐values from the sharp cut‐off model. The calculated results are also then compared with the experimental data. It is found that the R3Y interaction gives a reasonable agreement with the data.

12C + 12C反应的融合动力学：相对论平均场方法中的天文学兴趣

的¹² C +  ¹² C ^聚变反应起着恒星演化的后期阶段一个显著作用。为了更好地理解所涉及的演化，必须了解相应的聚变裂变动力学和反应特性。在目前的分析中，我们使用著名的M3Y研究了该反应的融合截面以及S因子，最近研究了R3Y核子-核子（NN）势以及相对论性的平均场密度。折叠方式。使用NL3 ^*参数集计算密度分布和微观R3Y NN电位。所述ℓ -总结黄模型被用于研究了聚变截面，具有ℓ_最大锐截止模型的值。然后将计算结果与实验数据进行比较。发现R3Y相互作用与数据给出了合理的一致性。
