Abstract
We report on craters formed by individual 3 MeV/u Au qini⁺ ions of selected incident charge states qini penetrating thin layers of poly(methyl methacrylate). Holes and raised regions are formed around the region of the impact, with sizes that depend strongly and differently on qini. Variation of qini, of the film thickness and of the angle of incidence allows us to extract information about the depth of origin contributing to different crater features.
