摘要：

A study of the scattering of x rays from the liquid-vapor interface of ethanol at room temperature is reported and compared in detail to predictions based on standard continuum capillary-wave theory. Quantitative agreement is obtained and, in particular, the asymptotic power laws in the diffuse scattering characteristic of the algebraic decay of the density-fluctuation correlations at the surface are verified. The root-mean-square fluctuation of the liquid surface is obtained as 6.9 +/- 0.2 angstrom.
