摘要：

We report x-ray reflectivity measurements of liquid mercury between -36 degrees C and +25 degrees C. The surface structure can be described by a layered density profile convolved with a thermal roughness sigma(Tau). The layering has a spacing of 2.72 Angstrom and an exponential decay length of 5.0 Angstrom. Surprisingly, sigma(Tau) is found to increase considerably faster with temperature than the root Tau behavior predicted by capillary wave theory, in contrast with previous measurements on Ga and dielectric liquids.
