Abstract

We present a theory of radiation damage formation in alkali halides based on a new mechanism of dislocation climb, which involves the production of V-F centers (self-trapped hole neighboring a cation vacancy) as a result of the absorption of H centers of dislocation lines. We consider the evolutionof all experimentally observed extended defects: metal colloids, gas bubbles, and vacancy voids. Voids are shown to arise and grow large due to the reaction between F and V-F centers at the surface of halogen bubbles. Voids can ignite a back reaction between the radiolytic products resulting in decomposition of the irradiated material. (C) 1999 American Institute of Physics. [S0021-8979(99)00623-4].
