integrated intensities and diffuse X-ray scattering were measured from highly oriented pyrolytic graphite to characterize the thermal displacement parameters. Values of the mean square displacements (uz) of the carbon atoms perpendicular to the basal planes are large, whereas, the displacements are

A design is described with which elastic and sufficiently uniform compression of singlecrystal specimens by ~ 0.4 to 0.5% can be achieved at liquid helium temperatures. The provision of a sliding side support for the specimen, which prevents shear deformations arising in the compression process, mak
The linear dimensional changes of anisotropic and near-isotropic graphites were measured after irradiation in the range 300 to 1500ยฐC to 3.3 x 102r n/cm" (E > 0.18 MeV). The presence of a nongraphitizing impregnant coke in an anisotropic needle-coke graphite increased its volume contraction, reduced
