Abstract

XANES studies make it possible to determine the geometrical parameters (interatomic distances and bond angles) around the X-ray absorbing atom. The environment of the absorbing atom is the primary cause for the XANES features. This is the reason these Characteristic features are clearly observed for disordered systems. XANES was used to determine the local structure in compounds. A systematic approach based on mathematical methods of solving inverse correlation and taking into account the specifics of XANES is now being developed.
