Local Structure Study of Lanthanide Elements by X‐Ray Absorption Near Edge Structure Spectroscopy.

This paper describes a systematic study of the spectra and local structures of lanthanide (Ln) L‐edge XANES. We found that Ln L1 and L3‐edge XANES spectra exhibit characteristic features correlated to their local symmetry through experimental and theoretical simulations. We also propose a simple local structure index criterion for a combination of XANES study and theoretical simulation. Possible solutions of intrinsic problems such as low resolution of characteristic features in the Ln L‐edge XANES and site distributions are also discussed. [ABSTRACT FROM AUTHOR]
