A companion paper presented arguments that support the applicability of a simple Ramsauer model to describe neutron total cross sections. Such a model yields a simple equation for the energy dependence of the cross section of a given nucleus and also allows extrapolation to nuclei of other A values. Fits of the Ramsauer form to very precise total cross sections recently measured over an extended energy range are presented. Very good fits are obtained for neutron energies between 6 and 60 MeV, suggesting that this approach will be useful for estimating cross sections in cases where experimental data are unavailable. Extension of this model to 120 MeV was only moderately successful.
