Astrophysical <i>S</i>-factor in a square-well potential model

Abstract

The astrophysical S-factor for the fusion of light nuclei, important for stellar nucleosynthesis reactions was analyzed within the framework of a model with a square-well potential. Using this model, one can obtain a good description of the experimental data in the sub-barrier energy region for the even-even nuclei fusion reactions in a mass number range of 12 ≤ А ≤ 28. Also, the functional dependencies for the systematics of potential parameters were obtained.
