Abstract

A study is performed on two types of static structures for disordered systems: one consists of atomic configurations of a Lennard-Jones liquid on either side of the ergodicity transition (G. Wahnström, Phys. Rev. A, 44 (1991) 3752) and the other of atomic configurations for as-quenched and annealed amorphous Pd52Ni32P16, derived from experimental diffraction data (M. Schaal, P. Lamparter and S. Steeb, Z. Naturforsh. A, 43 (1988) 1055) by the Reverse Monte Carlo technique. The static structures are analysed in order to find features that can be connected to the differences in atomic mobility. In amorphous PdNiP a free-volume effect is observable in both systems the irregularity of the nearest-neighbour shells is affected in a similar manner. This parameter was seen to be important for the atomic mobility in an earlier study by J.M. Delaye and Y. Limoge (J. Non-Cryst. Solids, 156-158 (1993) 982).
