Application of a simple Ramsauer model for neutron total cross sections for nuclear mass numbers A < 40

A recent paper discussed fits of the nuclear Ramsauer model to total neutro n 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 rec ent set of precision data in this mass range, Particular emphasis is placed on the elements of biological importance: carbon, nitrogen, and oxygen.
