Abstract
Complementary neutron diffraction and anomalous x-ray diffraction techniques are used to probe the nature and origin of local and intermediate-range order in cesium germanate glass. Both neutron and differential x-ray structure factors reveal peaks at low wave vector associated with intermediate-range order. The real-space correlation functions show that the local interatomic correlations in the glass are similar to those in the reference crystal Rb2Ge4O9 and imply a homogeneous distribution of Cs+ cations.Keywords
