University of Groningen Characterization of the size and orientation of Na and Cl-2 nanocrystals in electron irradiated NaCl crystals by means of synchrotron radiation

Samples of synthetic NaCl crystals have been exposed to doses of electron irradiation up to 10−2 TGy (1 Trad) at about 100 ◦C, and studied subsequently at T = 95 K by means of synchrotron radiation (SR). In addition to the earlier established Kurdjumov–Sachs orientation relationship (K–S OR) for Na precipitates, the following OR is revealed between solid chlorine and the host NaCl crystal system: {001}Cl ‖ {001}NaCl, 〈110〉Cl ‖ 〈110〉NaCl. The size and shape of the Cl2 precipitates has been studied as a function of the amount of radiation damage (i.e. the concentrations of Na and Cl2).
