ROENTGENORGRAPHIC EFFECTS IN NEUTRON-IRRADIATED CRYSTALS,

Abstract

The paper deals with structural disturbances of a crystal lattice caused by neutron irradiation. Diamond, corundum, silicon, germanium, aluminum, and molybdenum were the objects of investigation. A comparison is made of the increase of lattice constant and the intensity of diffuse scattering in these materials. Special treatment is given to the unusually large expansion of the diamond lattice following irradiation. Neutron irradiation of crystals leads to an increase of lattice constant and causes the appearance of temperature-independent diffuse scattering on x-ray photographs. Annealing leads to a decrease in growth of the parameter and to a gradual attenuation of the effect of diffuse scattering.
