Neutron inelastic scattering from /sup 54,56/Fe

Differential cross sections for inelastic scattering of neutrons to numerous levels in /sup 54,56/Fe have been measured at incident neutron energies of 11 and 26 MeV. The data have been analyzed in terms of a collective model using a distorted-wave Born approximation as well as a full coupled-channels treatment. Analysis has also been performed with a microscopic folding model using an energy- and density-dependent effective interaction. Both collective and microscopic analyses have also been applied to inelastic proton scattering in the same energy region in order to extract information on the isospin nature of the measured excitations.
