Experimental study of the density profile in the liquid–vapor interface of mercury
Abstract
The x-ray reflectivity (for Mokα radiation) of liquid mercury as a function of angle of incidence has been measured up to 10 θc (the critical angle θc being equal to 3.76 mrad). Since the x-ray reflectance is a probe of the properties of the surface, the data can be used to discriminate among models of density profiles in the liquid–vapor interface.
