Figure 9
The specular reflectivity of the orthoclase (001)–water interface as a function of momentum transfer (in units of Å−1), measured in contact with deionized water (circles) and with a 0.01 M solution of RbCl (triangles). Note that the differences in reflectivity data are well resolved for the two solution conditions. The solid lines are fits to the data. Also shown (diamonds) is the background level at each Q, scaled to indicate the signal-to-background level for each CCD image for the orthoclase in contact with water. |
