Figure 3
Scattering intensities recorded close to the critical angle from 9 wt% PS3 latex in D2O against a silicon surface with D22. Density measurements showed that the particles were dispersed in a 15:85 mixture of H2O:D2O. Using the scattering length density of this combination the critical angle measured with λ = 1.4 nm was 0.8°. The rectangles around the first-order Bragg peaks represent the regions of interest chosen to estimate the relative intensities plotted in Fig. 5. The intensities are normalized to the measurement time and shown on a loge scale. The vertical strip along the central part of Qx on the right side of the figure shows the integrated peaks as an example for [\theta_{\rm i}/\theta_{\rm c}] = 1.07.
