Intermediate structure in the neutron scattering cross sections of iron

Differential cross sections for the Fe(n, n), (n, n′), (n, n′γ) reactions were measured at incident energies between 1.43 and 2.15 MeV. Structure with intermediate widths was observed. The result was analysed by the doorway-state model, and the widths of the assumed doorway states were obtained. Spin and parity assignment of $\text{3}\text{2}$(⁺) was made to a doorway-state resonance at about 2.0 MeV.
