    Calculation of Cross-sections and Astrophysical S-Factors for Ni-62(alpha,n) and Ni-62(alpha,gamma) Reactions of Structural Fusion Material Nickel
    (Springer, 2016) Yildiz, Ercan; Aydin, Abdullah
    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.

    Calculation of cross-sections and astrophysical s-factors for the 63 Cu(α,n) and 63 Cu(α,γ) reactions
    (E D P Sciences, 2015) Yildiz, Ercan; Aydin, Abdullah; Sarpun, Ismail Hakki; Tel, Eyyup
    The cross sections and astrophysical S-factors of the Cu-63(alpha,gamma) and Cu-63(alpha,n) reactions have been calculated. The radiative alpha capture reaction cross sections was calculated in the incident energy range of 3 to 10 MeV and the (alpha,n) reaction cross sections was calculated in the incident energy range of 7 and 16 MeV. In these theoretical calculations, the TALYS 1.6 and NON-SMOKER codes were used. Also for these reactions, it was calculated the astrophysical S-factors which describe the possibility of reaction in low energies. Obtained results were compared to the experimental data taken from EXFOR database.

    Calculations of Cross-Sections and Astrophysical S-factors for the (alpha,n) Reactions of Some Structural Fusion Materials
    (Springer, 2017) Yildiz, Ercan; Aydin, Abdullah; Sarpun, Ismail Hakki; Tel, Eyyup
    Structural material selection in design of fusion reactors is very crucial. These structural materials should satisfy the hard conditions such as high thermo-mechanical stresses, high heat loads and severe radiation damage without compromising on safety considerations. The materials such as titanium, vanadium and chromium are used in the construction of fusion reactors. Therefore, it is important to examine these materials. Obtained results from the nuclear reactions using structural materials can be used for developing of these structural materials. For this reason, in this study cross sections of the Ti-46(alpha,n) Cr-49, Cr-50(alpha,n) Fe-53 and V-51(alpha,n) Mn-54 reactions have been calculated at 2-20 MeV energy range. In these theoretical calculations, the TALYS 1.8 and NON-SMOKER codes were used. Also, the astrophysical S-factors which describe the possibility of reaction in low energies were calculated. Results of our calculations were checked to the experimental data obtained from EXFOR database.

    Theoretical investigation of cross sections and astrophysical S-factors for the Mo-92(alpha,n)Ru-95 and Mo-94(alpha,n)(97) Ru reactions
    (E D P Sciences, 2016) Aydin, Abdullah; Yildiz, Ercan; Sarpun, Ismail Hakki
    Molybdenum is commonly applied as a constructive material in different types of nuclear reactors. The cross sections of the Mo-92(alpha, n) Ru-95 and Mo-94(alpha, n) Ru-97 reactions have been calculated at 5-20 MeV energy ranges. In theoretical calculations, the TALYS1.6 and NON-SMOKER codes were used. Also the astrophysical S-factors were calculated. Results of our calculations were checked to the experimental data obtained from EXFOR database.

    The (α,n) reaction cross-section calculations for some isotopes of iron group elements in the range of 5-20 MeV
    (E D P Sciences, 2017) Yildiz, Ercan
    Iron group elements (Sc, Mn, Fe, Co, Ni) are especially very important because structural material selection in design of fusion-fission reactors is very crucial. Obtained results from the nuclear reactions using structural materials can be used developing for these structural materials some isotopes. For this reason, in this study the cross sections of Sc-45(alpha, n) V-48, Mn-55(alpha, n) Co-58, Fe-54(alpha, n) Ni-57, Co-59(alpha, n) Cu-62, Ni-62(alpha, n) Zn-65 reactions have been calculated at 5-20 MeV energy ranges by using TALYS 1.8 and NON-SMOKER codes. Obtained results were compared experimental data from EXFOR database.
