Abstract

EXAFS measures the thermal variation of average interatomic distances, while Bragg diffraction and dilatometric techniques measure the variation of distances between average atomic positions. The difference not only gives information on vibrational motion perpendicular to the bond direction, but can be exploited to study the local behaviour in systems affected by negative thermal expansion. Recent results on copper, germanium and Ag₂O are presented and critically compared.
