Abstract: The freezing of capillary waves on glycerol surfaces is studied by in situ x-ray reflectivity measurements. A wide temperature range around the calorimetric glass transition temperature at T(g)approximate to186 K is investigated. For T>250 K the obtained surface roughness as a function of the temperature differs significantly from the value predicted by the classical capillary waves theory. Below the temperature Tapproximate to250 K the magnitude of the roughness remains constant. Furthermore, a large hysteresis, i.e., a large difference of the roughnesses measured during cooling and heating of the sample, is observed. These findings are discussed in terms of viscosity effects.
