Abstract : The transmission of slow neutrons through microcrystalline materials has been the subject of several investigations. However, the effect of nonrandom orientations of the microcrystals on neutron scattering has not been considered in detail. We shall develop a simplified scheme for taking account of the orientation effect when only a single symmetry axis needs to be considered. A comparison is made with the measurements of the transmission of slow neutrons through randomly oriented and extruded graphite. It is possible to obtain an estimate of the amount of crystal orientation in this instance.
