Polycarbonate, polyimide, and glass samples were irradiated with heavy
ions in the 11.4-14.0 MeV/amu energy range at the UNILAC of GSI. Afte
r etching and partly coating the specimens with a thin gold layer, ion
tracks were studied with scanning force microscopy, including imaging
in the lateral-force mode. Results on pore features such as the radiu
s as a function of etching time are presented.
