Figure 7
MD simulation of 4 keV Xe cascades in a-SiO2. (a) The diameters of various noble gas atoms are indicated by the arrows and the inset shows an enlarged view of the tail of the distribution; and (b) the variation of volume accessible to Xe as a function of the number of cascades (cumulative volume of voids with diameters larger than the Van der Waals diameter of Xe).
