Abstract

The results of a combination of neutron and x-ray diffraction measurements on normal and densified GeO₂ glass from which information about the partial structure factor S_ij(Q) for different element pairs (i,j) were obtained were reported. It was found that the greatest effects when the Ge-Ge correlations were eliminated and least when O-O correlations were eliminated. This result was surprising since previous discussions on intermediate range order (IRO) in network glasses have focused on cation-cation correlations.
