A revision of the data for angular distributions for elastic neuton scattering in oxygen and deuterium is presented. The kinetics of the (n,2n) reaction in deuterium is discussed and a Monte Carlo scheme for generating the energy and direction of secondary neutrons is given. Complete sets of the cross sections for both materials are tabulated.

The calculation of neutron transport in air requires an accurate knowledge of the neutron cross sections for nitrogen and oxygen. Existing direct measurement of the total elastic cross section for nitrogen is in marked disagreement with the value deduced by taking the difference between the total cross section and the sum of all partial non-elastic cross sections. This discrepancy in the available data indicates an error in the total-elastic measurement of 30% or in the total non-elastic cross section of 50%. A technique to measure differential cross sections for the small-angle (3 degrees to 15 degrees) scattering of fast neutrons has been developed and applied to a study of the scattering of 7.55 and 9.5 MeV neutrons from N, O, and C. Preliminary analysis of measurements obtained thus far show that the forward angle elastic scattering in nitrogen (theta
