Angular distributions of the analyzing power A/sub y/(theta) have been measured for neutron elastic scattering and for neutron inelastic scattering to the first 2/sub 1//sup +/ states of /sup 54,56/Fe and /sup 58.60/Ni at 10 MeV, and for /sup 54/Fe and /sup 58/Ni at 14 and 17 MeV. The differential cross sections sigma(theta) for the same processes were measured at 17 MeV for /sup 54/Fe and /sup 58/Ni. These measurements have been combined with other measurements of sigma(theta) and A/sub y/(theta) and also with total cross sections to form a sizable data set for incident neutron energies up to 80 MeV. This data set has been described in the context of the coupled channels formalism to determine the energy dependences of the various terms of the deformed optical potential. Some emphasis was placed on investigating the magnitude of the deformation parameter ..beta../sub so/ of the neutron spin-orbit potential and the possibility that it might be energy dependent.
