Measurement of (n, α) and (n, 2n) reaction cross sections at a neutron energy of 14.92 ± 0.02 MeV for potassium and copper with uncertainty propagation (vol 46, 014002, 2022)

Experimentally measured neutron activation cross sections are presented for the Cu-65(n, alpha) Cu-62m, K-41(n, alpha)Cl-38, and Cu-65(n,2n)Cu-64 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)alpha fusion reaction. The Al-27(n, alpha)Na-24 reaction was used as a reference reaction for the normalization of the neutron flux. The pre-calibrated lead-shielded HPGe detector was used to detect the residues' gamma-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.
