Calculation of Cross-sections and Astrophysical S-Factors for Ni-62(alpha,n) and Ni-62(alpha,gamma) 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 Ni-62(alpha,n) and Ni-62(alpha,gamma) 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 Ni-62(alpha,n) and Ni-62(alpha,gamma) 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.
