Abstract
Gamma irradiation or plastic deformation reduces the ionic conductivity of NaCl single crystals because of the decrease of the extrinsic cation vacancy concentration. Two steps in the thermal recovery of this vacancy concentration have been observed to occur between 200 degrees C and 620 degrees C in pulsed thermal annealing experiments. The ascription of these effects to dislocations and divacancy clusters acting as traps for the impurity-cation vacancy dipoles is discussed. (C) 1998 Elsevier Science B.V. All rights reserved.
