摘要: Abstract Energy loss spectrometry of ions transmitted through matter is hitherto known as a tool to probe the geometrical dimensions and/or density distributions within given small sample in one, two, or even three dimensions. We show here that energy can also be applied determine radial distribution latent ion tracks polymers. First test experiments Rutherford Backscattering (RBS) geometry are reported, where 2 MeV protons and α particles used self-created collodium films. Track overlapping leads rough surface structure which smoothens out with increasing irradiation dose.
