Abstract

Accurate analyzing power data have been obtained for scattering of 10- and 14-MeV neutrons from ${}^{54}{Fe}$ and ${}^{65}{Cu}$ , with use of a new combination of techniques to produce pulsed, polarized neutron beams. Parametrization with the conventional optical model yields a spin-orbit interaction which is consistent with that observed for proton-nucleus scattering. This combined experimental and theoretical study represents the most sensitive test of similarities between proton and neutron spin-orbit potentials for medium-weight nuclei.
