Study of radiolysis products in tracks over the distance from the ion trajectory in polyethylene terephthalate and polycarbonate

Abstract

Latent tracks and track-etched membranes micro- and nanosized entities are promising research objects. The peculiarity of such structures is that they are discrete in nature. As the distance from the track axis increases, the physical and chemical characteristics of these entities change to their original values. The track size also depends on the mass and energy of energetic ions. For example, the maximum size of Kr ions with an energy of 1 to 2 MeV/amu is 50 nm according to preliminary data. Changes in the track area over the distance from the ion trajectory have been studied in this work.
