Determination of ion track radii in amorphous matrices via formation of nano-clusters by ion- beam irradiation

We report on a method for the determination of ion track radii, formed in amorphous materials by ion- beam irradiation. The method is based on the addition to an amorphous matrix of a small amount of foreign atoms, which easily diffuse and form clusters when the temperature is sufficiently increased. The irradiation causes clustering of these atoms, and the final separations of the formed clusters are dependent on the parameters of the ion-beam. Comparison of the separations between the clusters that are formed by ions with different properties in the same type of material enables the determination of ion-track radii.
