Abstract

The isotopic substitution method of neutron diffraction is applied to study the co-ordination environment of Ag in bulk-quenched glassy AgAsS2. The silver has nearest-neighbour sulphur atoms with rAgS = 2.54±0.01 and nAgS = 3.2±0.1 in addition to pronounced second-neighbour (2.82Å≤r≤5.2Å) and intermediate-range (5.2Å≤r≤8.0Å) correlations. The observation of Ag correlations beyond the first sulphur shell is in direct contrast to the EXAFS results of Steel et al1.
