Abstract
WE report here the development of a molecular scanner, a device that yields information about the spatial variations in emission of neutral atoms or molecules from the surface of a heterogeneous sample. We believe that such instruments may be of great value in science and engineering, but we envisage a more refined apparatus. Here we merely describe the principle. We report the variation in evaporation in a scan across a sample consisting of alumina fragments embedded in potassium feldspar glass (K2O.Al2O3.6SiO2, melting point 1,550 ± 10° C). We believe this is the first report of the observation of surface features by molecular emission, as opposed to light or charged particles.
