PULSE X-RAY-DIFFRACTION STUDY OF SHOCK-COMPRESSED NACL

Results of X-ray diffraction study of shock-compressed NaCl single cry stals of <100> orientation are suggested. A new geometry of X-ray diff raction survey specially developed for studies of a single crystal sam ple in the monochromatic radiation was employed to obtain a multi-peak diffraction pattern allowing the complete determination oi the compon ents of the crystal strain tenser. During the compression of the cryst als their state was continuously monitored by velocity interferometer. The diffraction patterns obtained at the different regions of the pla stic wave front evident that the crystal is able to maintain the state of unidimensional compression up to the strain level of about 0.06.
