Description
The 12C+12C fusion reaction plays a crucial role in stellar carbon burning and the evolution of massive stars. However, significant uncertainties remain in the fusion cross sections and reaction rates at astrophysical energies. In this work, we systematically investigate the performance of various versions of the proximity potential formalism in describing the 12C+12C fusion process. Fusion cross sections are calculated using the one-dimensional barrier penetration model and compared with available experimental data. The corresponding astrophysical S-factors and thermonuclear reaction rates are also evaluated. Statistical analyses are performed to identify the potential models that best reproduce the experimental measurements. The results provide improved constraints on the 12C+12C reaction and help reduce nuclear physics uncertainties in stellar evolution calculations.
Keywords: Nuclear astrophysics, 12C+12C fusion, carbon burning, proximity potential, reaction rates.
