Abstract：
The cross sections for ⁶³Cu(n,α)⁶⁰Co reaction are measured by taking the cross sections of ²⁷Al(n,α)²⁴Na reaction as the reference values and using the activation method in the neutron energy range of 13.6-14.8 MeV. The values of 583 ±3.1,563 ±2.4,53.4 ±2.0,50.8 ±1.9,48.4 ±1.7 and 47.4 ±1.7 mb are obtained at the 13.64,13.79,14.03,1433,14.60 and 14.80 MeV neutron energies, respectively. The results are compared with the published data. Neutron energies in the experiment were determined by means of the method of cross section ratios for ⁹⁰Zr(n,2n)⁸⁹Zr and ⁹³Nb(n,2n)⁹²mNb reactions.
