Abstract

Damage initiated by halogen recoil atoms in mixed hexabromochlorometallates has been evaluated with the help of the impact-induced multiple Ligand Abstraction (IMULA) model. The essential reactions within the scope of the model are (1) primary retention for recoil atoms with energies below some threshold of displacement energy, (2) halide-halide substitution reactions (billiard ball reactions), (3) reactions in which two or more halide ligands are displaced with subsequent reoccupation of the vacancies by adjacent halides and (4) formation of interstitials which form free halide during the dissolution of the irradiated substances. It was found that for all recoil atoms and both potassium hexabromochlorometallates the contributions of the different reaction channels are very similar: (1) 4–18% (2) 40–50%, (3) 25–30% and (4) 12–20% These results do not differ essentially from results so far obtained in mixed crystal systems.
