Abstract
The study of neutron-induced threshold reactions is important for validating nuclear models, ensuring accuracy in theoretical frameworks, and finding practical applications, particularly in fusion reactor technology (FRT) and accelerator-driven systems (ADSs). This research focuses on measuring neutron-induced reaction cross sections on , specifically the and reactions. Current data for these reactions are limited in the case of the () reaction, and in the case of the () reaction exhibit significant discrepancies, especially for the neutron energy range below 12 MeV. Our study addresses these data gaps and discrepancies by providing new cross-section measurements. To address these gaps, we performed new cross-section measurements using white neutron beams at the Weapons Neutron Research (WNR) facility at Los Alamos Neutron Science Center (LANSCE), contributing to a more detailed understanding of neutron-induced reactions on below 20 MeV. The experimental setup, data analysis, and results are discussed, highlighting the improved agreement between our new data and theoretical calculations.
