Cross section measurements of (n, ) (n, n' ) and (n, p) reactions for ⁶⁵Cu at 14 MeV neutrons

The cross sections of the Cu-65(n, alpha)Co-62m, Cu-65(n, n'alpha)Co-61 and Cu-65(n, p)Ni-65 reactions have been measured relative to Fe-56(n, p)Mn-56 reaction at 14 MeV neutron energy through neutron activation method followed by offline gamma-ray spectrometry. The 14 MeV neutrons were produced via the H-3(d, n)He-4 fusion reaction based on K-400 D-T neutron generator at China Academy of Engineering Physics (CAEP). The neutron energies were determined by the cross-section ratios for the Zr-90(n, 2n)Zr-89 and Nb-93(n, 2n)(92)mNb reactions. The cross sections measured in the present work are compared with the earlier reported cross sections available in the EXFOR database, evaluated nuclear data and theoretical results calculated by TALYS-1.95 code.
