Total cross section values for electrons scattered by atoms and molecules can be obtained by adding the total inelastic cross section to the total differential elastic cross section. We compare these values with experimental values for nitrogen and carbon dioxide. For methane, we compare with experimental values from positron scattering. The agreement is excellent for nitrogen between 40 and 1500 eV and for carbon dioxide between 100 and 500 eV.
