From an analysis of the X-ray Debye-Sc6herrer lines from fine gold j>articles withthe mean size of TOO A, the mean square atomic displacement,<&"Y>, was deter-mined at several temperatures in a range from 112 to 298 K. The temperaturedependence of (z') was analysed on the basis of the Einstein apprc?ximation forthe thermal vibrations of atoms and a characteristic temperature 0.=143.J.3 Kwas obtained. This is 15 '3 less than the Debye temperature 0.=I68 K for thebulk crystal. It was found that the observed<Z/'>includes the temperatureindependent component, impling the existence of some kind of static latticedistortions. The contribution from such lattice distortions depends 011 the prepa-ration condition of fine gold particles.
