Surface roughness of water measured by X-ray reflectivity
TL;DR: The roughness of the liquid-vapor interface for pure water was measured by a technique of x-ray reflectivity and a fit to the data by a theory with only one adjustable parameter obtains 3.2 \AA{}A for the root-mean-square roughs of the water surface.
Journal ArticleDOI
Auger-electron emission resulting from the annihilation of core electrons with low-energy positrons.
TL;DR: The first demonstration of positron-induced Auger-electron spectroscopy is reported, with implications of the extremely high signal to background and several important advantages of this process for surface analysis are suggested.

TL;DR: In this article, a room-temperature electrodeposition technique was devised to synthesize thin films on indium tin oxidecoated glass slides, based on a nonaqueous ethylene glycol bath containing anhydrous and elemental sulfur.
Journal ArticleDOI
Low-Energy Positron Diffraction from a Cu(111) Surface
TL;DR: The first observation of low-energy positron diffraction from a solid surface is reported in this paper, where slow (20-400-eV) monochromatic positron beams were focused onto a Cu(111) surface and their elastically scattered distributions detected with a channel electron multiplier.
