Abstract

Explaining the origin and evolution of elements is one of the most important problems in astrophysics. The r-process in the current nucleosynthesis scenario; roughly responsible for the production of half of the nuclei heavier than iron. 8Li(α,n)11B reaction plays an important role in the r-process of this scenario because of being a cosmic radiation induced  reaction. In particular, it is important to know the change with energy in the low energy zone for testing the accuracy of the model calculations. In this study, the astrophysical S-factors of the 8Li(α,n)11B reaction and the probability of reaction at low energies were calculated in the 0-5 MeV energy range. TALYS 1.8 code was used for the theoretical calculations. The obtained theoretical values were compared with experimental data obtained from the EXFOR database.
