Differential cross sections for the elastic and inelastic scattering of neutrons from /sup 54,56/Fe have been measured in the 11-26 MeV region. The elastic scattering data are analyzed in terms of a phenomenological optical model. The present data along with additional proton elastic scattering data are analyzed in terms of microscopic optical model potentials. Inelastic scattering data for both neutrons and protons are analyzed using both collective and microscopic models. Elastic neutron differential cross sections have been measured for /sup 54/Fe at five energies and for /sup 56/Fe at three energies. Inelastic cross sections have been measured for ten different excited states in /sup 54/Fe and for eleven states in /sup 56/Fe. The energy and isospin consistency of the microscopic optical model is established. In the collective model analysis /sup 54/Fe is found to vary from the ideal vibrational model, while /sup 56/Fe is well described as an asymmetric rotor. The isospin nature of the first 2/sup +/ excitations in both /sup 54,56/Fe is quantified in both collective and microscopic analyses.
