Natural cordierite crystals were irradiated with Xe ions of 1.465 GeV kinetic energy and fluences ranging from 10(8) to 10(12) ions/cm(2). Raman spectra of the surface and line scans along the trajectory of the ions have been recorded. At a fluence of 10(12) ions/cm(2) the colour of the originally blue sample changed to yellow and the Raman spectrum shows distinct band broadening. Irradiation also alters the content and nature of volatiles (CO2, H2O) incorporated into structural channels. Similar effects have been described for cordierite affected by natural irradiation from a decay processes. (C) 2008 Elsevier B.V. All rights reserved.
