摘要

Experimentally measured neutron activation cross sections are presented for the 65Cu(n,α)62mCu,41K(n,α)38C1,and 65Cu(n,2n)64Cu reactions with detailed uncertainty propagation.The neutron cross sections were measured at an incident energy of 14.92 ± 0.02 MeV,and the neutrons were based on the t(d,n)α fusion reaction.The 27Al(n,α)24Na reaction was used as a reference reaction for the normalization of the neutron flux.The pre-calib-rated lead-shielded HPGe detector was used to detect the residues' y-ray spectra.The data from the measured cross sections are compared to the previously measured cross sections from the EXFOR database,theoretically calculated cross sections using the TALYS and EMPIRE codes,and evaluated nuclear data.
