Abstract : Cesium metal was deposited from the vapor on a large-grained rhenium substrate. Both the wetting of the substrate by the cesium and the mode of growth of solid films of cesium are dependent upon the crystal face exposed by the various grains of rhenium. The experiment was done in a sealed-off glass tube which had a residual gas pressure of 10 to the -9th power torr before cesium was admitted. Both the wetting and the mode of film growth were dependent upon monolayer amounts of impurities. Epitaxial relationships were observed to exist between many of the rhenium grains and the deposited cesium. (Author)
