Abstract : Irradiation by X rays of NaCl crystals produces F centers and interstitial ions. The former are detected by measured changes in optical absorption, the latter by measured changes in the velocity of sound. A simple theory of dislocation pinning by interstitials accounts well for the changes in acoustic velocity. Current theories of initial-stage and final-stage coloration are justified by the results; estimates of the rates of defect production are made. (Author)
