Dynamic processes in metal nanoparticles under irradiation

Dynamic processes occurring in a nanoscale metal object during the implantation of high-energy ions are studied in detail. It is shown that the elastic and thermoelastic lattice responses to irradiation form force factors considerably affecting the evolution of the defect-impurity system, which, in turn, leads to a decrease in the number of structural defects. Quantitative estimates of the spatial redistribution of defects resulting in their emergence on the surface are obtained. Such self-organization of nanoparticles under ionizing radiation forms a basis for the production of nanostructured radiation-resistant materials capable of sustaining a long-term intense radiation load.
