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