• A specially designed evaporater and cryostat were equipped in a diffraction specimen chamber of an HU-11A electron microscope. In this apparatus 99.999 % silver granules were evaporated onto a polished polycrystalline copper substrate at various temperatures and prepared films were observed at 77°K by the reflection electron diffraction. The films condensed at 77°K with a deposition rate of about 20 Å/sec. showed a remarkable fiber texture in which the <111> and <100>: axes of the crystallites are normal to the substrate surface. This texture disappeared when annealed at 373°K. On the other hand, films prepared at 105°K and the room temperature showed normal Debye-Scherrer patterns with no or another very weak fiber texture. On the basis of these experimental results, the formation mechanism of the low temperature fiber structures was discussed by taking into account of the effects of the deposition and reevaporation rates and the surface diffusion on the growth of the crystallites.
