Abstract
The waves excited in thermal equilibrium on the surface of a liquid show up in X-ray scattering experiments in a diffuse component with center at the specular beam. They can be studied with the aid of a Kratky-camera carrying out rocking-scans. Results obtained for poly(vinylacetate) agree with the theoretical prediction. Evaluation of the data yields the surface tension.
