Top panel: ⁵⁶Fe(n,γ)⁵⁷Fe cross-section as function of the neutron incident energy. The black squares correspond to EXFOR data [29], the full black line is the prediction obtained using the default level density model implemented in the TALYS code [1,30], the red dotted line using the combinatorial level density model of Ref. [31] and the green dashed line the combinatorial level density model of Ref. [32]. Bottom panel: ratio between the strength functions obtained after the normalization deduced from equation (3) is applied and the strength function corresponding to the default level density option.
