Physica A 200(1-4): 50-64.0378-4371http://nrs.harvard.edu/urn-3:HUL.InstRepos:10357541X-ray reflectivity experiments on the structure of the liquid-vapor interface that were recently carried out by our group will be described. Systems that were studied include thin wetting layers adsorbed onto a solid substrate, the interfacial electron density profile of superfluid \(^4\)He, and preliminary measurements of the roughness of the surface of liquid gallium. The fundamental theoretical background to these experiments will be reviewed.en-USJournal Article10.1016/0378-4371(93)90504-W
