Fig. 31: The ratio of the transmitted to incident intensity through the two phase solution, shown in Figure 30, as a function of the height of the sample container relative to the X-ray beam. Data are presented for photon energies of 15.3 keV (above the Rb K- absorption edge; solid curve) and 15.1 keV (below the Rb K- absorption edge; broken curve). The inset shows the Rb-K edge absorption jump at 15.2 keV, and EXAFS signal, for the dilute phase.
