We present new data on the 63Cu(γ, n) cross section studied using a quasi-monochromatic and energy-tunable γ beam produced at the Shanghai Laser Electron Gamma Source to resolve the long-standing discrepancy between existing measurements and evaluations of this cross section. Using an unfolding iteration method, 63Cu(γ, n) data were obtained with an uncertainty of less than 4%, and the inconsistencies between the available experimental data were discussed. The γ-ray strength function of 63Cu(γ, n) was successfully extracted as an experimental constraint. We further calculated the cross-section of the radiative neutron capture reaction 62Cu(n, γ) using the TALYS code. Our calculation method enables the extraction of (n, γ) cross sections for unstable nuclides.
