Dependence of neutron total cross sections on energy for 100 <= E-n <= 500MeV and mass number for 7 <= A <= 238

Two recent measurement programs have yielded an extensive body of neutron t otal cross-section data for a number of targets at energies up to 500 MeV. Recently, it has been shown that the simple Ramsauer model provides a good description of the data up to 120 MeV. The parameterization developed in th is energy region did not do as well above this energy. The data in the regi on 100 less than or equal to E-n less than or equal to 500 MeV are examined and it is concluded that a simple parameterization can describe the data w ell. The applicability of the Glauber model is tested in the energy region above 150 MeV.
