Representative ⁵⁶Fe results employing γ-ray detection following inelastic neutron scattering from the (n, n′γ) reaction at the white-source laboratory nELBE to extract level cross sections over a wide range of energies. γ-ray production cross sections are measured (top) and feeding is subtracted to extract level cross sections (bottom) [21]. Other good examples are the ⁵⁶Fe(n, n′γ) data of Negret [15] and the ²³Na(n, n′γ) data of Rouki [16] taken at GELINA.
