Calculation of Cross-sections and Astrophysical S-Factors for 62Ni(α,n) and 62Ni(α,γ) Reactions of Structural Fusion Material Nickel

Abstract

Nickel is an important element in fusion reactor technologies and astrophysical applications. Therefore, the knowledge of astrophysical S-factors and cross-sections on nickel isotopes is needed. In this work, the cross sections of the 62Ni(α,n) and 62Ni(α,γ) reactions have been calculated. The alpha capture cross sections was calculated up to 10 MeV. In these theoretical calculations, the TALYS 1.6 and NON-SMOKER codes were used. Also for the 62Ni(α,n) and 62Ni(α,γ) reactions, we calculated the astrophysical S-factors that determine the probability of reaction in low energies. Results of our calculations were checked to the experimental data obtained from EXFOR database.
