Structure of Nanometer Wide Heavy-Ion Tracks in Muscovite

Article Preview

Abstract:

Radial electron densities within 63-67 μm long ion damage trails, latent ion tracks, created in {001} muscovite by irradiation with 11.1-28.7 MeV/A U and Pb ions, have been derived by small-angle X-ray scattering. Track diameters are 8.0-10.2 nm. The tracks exhibit continuous and uniform electron density decrease of ~4%. Complementary microscopy has revealed loss of atomic order in the tracks. These ion-induced effects undoubtedly accelerate preferential through track permeability of inert and corrosive agents, a property that is important for track applications.
