Theoretical Predictions of Excitation Functions of Neutron-Induced Reactions on 6Li, 9Be, 12C and 23Na Nuclei at Low Energies

Abstract

In the present work, the excitation functions of neutron reactions 6Li(n,p)6He, 9Be(n,α)6He, 12C(n,p)12B, 12C(n,α)9Be, 23Na(n,p)23Ne, 23Na(n,2n)22Na and 23Na(n,α)20F produced by the incident neutrons were studied for the investigation of fusion structural materials. Tel et al. formulae (for sodium isotopes), the codes ALICE–ASH and CEM03.01 (for all nuclei) were employed for the obtaining of cross-sections. In addition, hybrid model and geometry-dependent hybrid model with pre-equilibrium emissions, and Weisskopf Ewing model with the equilibrium emissions, and the cascade-exciton model with cascade interactions were used to calculate the excitations curves. The obtained results and Tendl-2011 library data were compared with the experimental literature values. Finally it is to mention that the cross-section data obtained may be useful for the safety design of future fusion reactors.
