Study of the Papyex structure using neutron Compton scattering
Abstract
The neutron Compton scattering technique (NCS) was utilized for a precise determination of the randomly oriented crystallites fraction in partially oriented graphite. This was done by measuring the effective temperatures of the C-atom along and perpendicular to the graphite planes in a sample of Papyex and comparing the results with those obtained from a highly oriented pyrolytic graphite (HOPG) sample. The half-width at half-max of the oriented fraction of crystallites (mosaic spread) was found to be (11.0±0.6)°, while the randomly oriented fraction was found to be (26.2±1.6)%.
