| Abstract: | Localized phonon modes in quench-condensed Pb.9In.1 films, annealed at several temperatures up to 300 K, were studied by the method of superconductive tunneling. No localized
modes could be seen in very disordered films. Structure from such modes first appeared as the crystallite grains size increased.
