Figure 7
Reflection profiles of liquid surfaces for X-ray incident angles α = 0.9 and 1.2°. The solid and dashed curves represent the theoretical predictions based on the capillary-wave model and are calculated using equations (5) and (6). Both of the observed intensities for water (circles) and the aqueous [C12mim]Cl solution (triangles) exhibit good agreement with those for the capillary-wave model. |
