Özet

© 2016, Springer Science+Business Media New York.Silver plated shields are used in components and structures of fusion reactors that may be effected due to the huge radiation. For this reason, we focused on excitation functions of 107,109Ag on alpha induced reactions. For simplicity to examining the events of nuclear physics, nuclear reaction codes such as ALICE/ASH, TALYS, CEM, EMPIRE, PCROSS, GEANT4 and FLUKA that includes different models have been used for many years. In this study, the cross-sections of (α,xn) reactions, where x = 1–5, for 107,109Ag by using nuclear reaction codes ALICE/ASH and TALYS 1.6 were computed. Hybrid and Geometry Dependent Hybrid Models were used in ALICE/ASH whereas Two-Component Exciton Model was used in TALYS 1.6 reaction codes. Energy ranges of alpha particles for 107Ag and 109Ag were taken into computations as 9.2–96.8 and 10.2–71.2 MeV, respectively. Computed results are also compared each other and with experimental data existing in the literature for each reaction.
