Structure in the spectra of neutrons emitted from iron upon bombardment with 14.6 MeV neutrons has been investigated and explained in terms of excitation of levels in ${}_{}{}^{56}{}_{}{}^{}\mathrm{Fe}$. The energies of scattered neutrons have been measured by the time-of-flight technique based on the associated particle method. The observed excitations have been correlated with the reported levels in a satisfactory manner. Evidence for new excitations at 8.8±0.2, 9.8±0.1, 10.2±0.1, 12.44±0.03, and 12.52±0.03 MeV has been obtained. The excitation of possible components of the M1 giant resonance in ${}_{}{}^{56}{}_{}{}^{}\mathrm{Fe}$ is discussed.
