摘要：

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)degrees, while the randomly oriented fraction was found to be (26.2 +/- 1.6)%.
