✦ Synopsis

is quite distinct from that given by randomly oriented copper crystals, the (111) copper ring and the (100) graphite ring are very nearly co-incident; di,,(Cu)/ d,,,(graphite)=0.98. Thus if only the inner diffraction rings are considered, the presence of an enhanced (100) ring in addition to an unchanged (002) ring might be attributed either to the development of graphite crystallites with some preferential orientation of the basal plane parallel to the film or to the presence of copper in addition to randomly oriented graphite.
