Figure 6
(a) Intensities of the SiO2 suspension at different sample-to-detector distances. Symbols are the data. Thick solid lines are the fittings based on equation (23). Thin solid lines are obtained by fitting the local minima with a stretched exponent, describing the contribution of multiple scattering. Data are displaced by a factor of ten for clarity. (b) The best-fit exponent versus sample-to-detector distances varying from 53 mm to 203 mm for the silica 0.45 µm suspension. |
