The temperature independent diffuse scattering of X-ray by a diamond lattice, in which a few carbon atoms are missing or have been replaced by foreign atoms of valency four is investigated. By the method given by Matsubara the intensity of diffuse scattering is calculated in terms of the force constants which are related to changes in bond length and of bond angle. The diffuse patterns observed by Lonsdale and Smith in natural diamonds are of streak or spike type but ours are of lemniscate type. Our patterns may be observed in radiation damaged diamond crystals.
