Abstract : Thin films of amorphous gallium, iron and nickel have been prepared by low temperature condensation in high vacuum, and a transmission electron diffraction study of these films has been undertaken. The radial distribution analysis of the patterns composed of diffuse halos has been carried out in order to investigate the local atomic arrangement in amorphous gallium, iron and nickel. Wr = ρr-ρ0 experimentally derived has been compared with Wr-s calculated from several structural models, leading to the conclusions that the structure of amorphous gallium is considerably similar to that of highly disordered β-gallium and that the structures of amorphous iron and nickel are, to a good approximation, represented by a dense random packed structure.
