摘要：

The formation of complex ions and molecules created in alkali bromides after X-irradiation at room temperature are studied by means of Resonant Raman Scattering. In NaBr, RbBr and CsBr, Br3-type defects are formed. In NaBr only, clusters of bromine, (Br2), are also observed. The process of halogen clustering is related to the formation of vacancies during the irradiation in the cationic sublattice. For comparison purpose, it is shown that similar results are obtained in a mixed iodide crystal, Kx Rb1 1-x1, in which iodine aggregates are not observed whereas they are in KI irradiated in similar conditions. © 1991, Taylor & Francis Group, LLC.
