英文摘要 | This work reports on the theoretical studies of defect production and annealing induced by electronic energy loss S-e in pure metal. The selected metal was a-iron in which irradiation effects produced by swift heavy ions have been well studied experimentally by Dunlop et al. [Nucl. Instr. and Meth. B 90 (1994) 330]. According to thermal spike model in metals and taking into account the principles of ion-solid interactions and thermal atomic jumps and migrations in solid, we have done numerical calculations of spatial distributions of vacancies and interstitials created by nuclear collisions, concentration-dependent thermal migration and recombination of existed defects and thermal defect generation for given swift heavy ion irradiations. The calculated results suggested that threshold S-e values for defect annealing and production were about lj and 38 keV/nm which are in agreement with experiments. The comparison of damage efficiencies deduced from our numerical calculations with experimental ones have shown that S-e induced defect production and annealing in pure metal can be a result of thermal transient process.
