qualitative interpretation of the experimental data for total neutron cross sec-
tions by Feshbach etal. (1954). e quantitative tting of the experimental data
was later considerably improved by the introduction of a diuse-surface optical
model with a rounded well potential (Melkano etal. 1957). For 14 MeV neutron
elastic scattering, it appears that the best ts so far are obtained by Bjorklund
and Fernbach (1958) using a rounded well potential to which is added a spin-
orbit term: As was shown by (Begum and Galloway 1979) the polarization of
14.2 MeV neutrons elastically scattered throu ...
