GISAXS pattern from an Au + Cu-implanted silica (implantation fluence = 3×1016 ions cm-2 for each ion species, implantation energy = 90 keV and 190 keV for Cu+ and Au+ ions, respectively). The data were collected on the ID10B beamline at ESRF, using an 8.0 keV X-ray beam and scanning horizontally a position-sensitive linear detector (0.05° step) to collect the two-dimensional pattern. Here a uniform ring is evident, indicating a three-dimensional distribution of particles. The angular scale, indicated below the scattering ring, is identical for the x and y directions and 1° corresponds to 0.07 Å-1. |
