Abstract

The anomalous X-ray scattering (AXS) technique was used to obtain the environmental radial distribution function (RDF) around a germanium in Ge02 glass. By combining the environmental and ordinary RDFs of GeO2glass, germanium was quantitatively shown to be surrounded by four oxygens at a distance of 0.174 nm and to share its corners in order to form a three dimensional tetrahedral network structure. A possible atomic arrangement of GeO2glass in near neighbor region is also proposed by refining structural parameters using the least-squares variational method.
