Electron Diffraction Study on Polish Layers of Gold, II

Abstract

Polish layer of gold was examined by means of the transmission method of electron diffraction. The diffraction pattern from the highly polished layer of gold (the Beilby layer) consists of three haloes, as reported in the previous paper (J. Phys. Soc. Japan 12 (1957) 151). The radial distribution function of atoms in the layer was calculated by Fourier transformation of the observed intensity. The observed intensity was compared with those calculated from appropriate models of atomic arrangement. It was found that the Beilby layer has an amorphous arrangement in which the first and the second coordination number are about 10 and 8, respectively.
