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 $^{68}\mathrm{Zn}$, specifically the $^{68}\mathrm{Zn}{(n,p)}^{68}\mathrm{Cu}$ and $^{68}\mathrm{Zn}{(n,\ensuremath{\alpha})}^{65}\mathrm{Ni}$ reactions. Current data for these reactions are limited in the case of the ($n,p$) reaction, and in the case of the ($n,\ensuremath{\alpha}$) 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 $^{68}\mathrm{Zn}$ below 20 MeV. The experimental setup, data analysis, and results are discussed, highlighting the improved agreement between our new data and theoretical calculations.
