Abstract : Calculations of the passage of neutrons through media which do not contain hydrogen are more difficult than the corresponding calculations for hydrogen-containing media. This can be explained by the fact that, in the first place, for very many elements the magnitudes of the neutron cross sections are known to have substantial errors (10-15%), while the differential cross sections for elastic and inelastic scattering have only been investigated within finite energy ranges. Therefore, solutions of practical problems which involve the passage of neutrons through media which do not contain hydrogen are obtained by using the purely experimental information which has been accumulated to date.
