Cross-section measurements for the ⁵⁷Fe(n,nγ )⁵⁷Fe and ⁵⁷Fe(n,2nγ )^56Fe reactions

A neutron inelastic scattering experiment was performed on an enriched ⁵⁷Fe sample at the Geel Electron Linear Accelerator neutron source using the Gamma Array for Neutron Inelastic Scattering spectrometer. Several γ -production cross sections were determined, but the first transition (14.4 keV) could not be detected owing to the steadily increased γ background at low energies. Consequently, we use an interplay between experimental data and carefully tuned theoretical calculations to generate the total inelastic cross section.
