Measurement of ( n , α ) and ( n , 2n ) reactions cross section at neutron energy 14.92 ± 0.02 MeV for potassium and copper with uncertainty propagation

The experimentally measured neutron activation cross sections are presented for the \begin{document}$^{65}{\rm{Cu}}$\end{document} (n,α) \begin{document}$^{62m}{\rm{Cu}}$\end{document} , \begin{document}$^{41}{\rm{K}}$\end{document} (n,α) \begin{document}$^{38}{\rm{Cl}}$\end{document} and \begin{document}$^{65}{\rm{Cu}}$\end{document} (n,2n) \begin{document}$^{64}{\rm{Cu}}$\end{document} reactions with detailed uncertainty propagation. The neutron cross sections are measured at an incident energy of 14.92 ± 0.02 MeV. The neutrons were based on the t(d,n)α fusion reaction. The \begin{document}$^{27}{\rm{Al}}$\end{document} (n,α) \begin{document}$^{24}{\rm{Na}}$\end{document} reaction was used as a reference reaction for the normalisation of the neutron flux. The pre-calibrated lead-shielded HPGe detector was used to detect the residues' γ-ray spectra. The data from the measured cross sections are compared to the previously measured cross sections from the EXFOR database, theoretical calculated cross sections using the TALYS and EMPIRE codes, and evaluated nuclear data.
