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

摘要

In the present work, the excitation functions of neutron reactions ~6Li(n,p)~6He, ~9Be(n,α)~6He, ~(12)C(n,p)~(12)B, ~(12)C(n,α)~9Be, ~(23)Na(n,p)~(23)Ne, ~(23)Na(n,2n)~(22)Na and ~(23)Na(n,α)~(20)F 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.
