Application of a Simple Ramsauer Model for Neutron Total Cross Sections for Nuclear Mass Numbers A < 40

Abstract

A recent paper discussed fits of the nuclear Ramsauer model to total neutron cross sections for mass numbers A > 40 and for neutron energies between 6 and 60 MeV. These results are extended to nuclei of mass <40. A reasonably simple parameterization is found that gives a good representation of a recent set of precision data in this mass range. Particular emphasis is placed on the elements of biological importance: carbon, nitrogen, and oxygen.
