The quartz cryatals investigated were: natural Brazilian; "z-growth synthetic," with growth perpendicular to basal plane; and "z-face synthetic, with growth direction perpendicular to the z-minor rhombohedron of the seed plate. The crystals received doses of l0/sup 19/ to 10/sup 20/ nvt. The lattice spacing measurements were made by the back-reflection divergent beam method. The maximum induced strain for the z-cut crystals was approximately 0.6%; whereas, for x-cut crystals it was approximately 1.8%. The large strains found in the x-cut crystals were reflected by the conspicuous break-up of the x-ray line profile into multiple peaks, which is characteristic of a substructure formation. The maximum strain for the z-cut crystals was perpendicular to the c-axis while it varied somewhat for the x-cut crystals. The minimum strain for z-cut crystals was parallel to the c-axis; whereas, that of the x-cut crystals was perpendicular. An irradiation defect mechanism was proposed from a study of the x-ray line profile intensity distribution. (B.O.G.)
