X-ray absorption fine structure (XAFS) spectroscopy using synchrotron radiation

Journal of Physics: Conference Series, 2012
The X-ray absorption fine structure (XAFS) spectra are best recorded when a highly intense beam of X-rays from a synchrotron is used along with a good resolution double crystal or curved crystal spectrometer and detectors like ionization chambers, scintillation counters, solid state detectors etc.

Studies on Surface and Interface with X-ray Absorption Fine Structure (XAFS). Time Resolved XAFS Studies for Catalysts Preparation.

Hyomen Kagaku, 2002
Time resolved dispersive XAFS (DXAFS) is a useful method to elucidate changing structures and is applicable to investigate the structures of short living species during chemical reactions. We applied this method to the chemical study of catalysts preparation.

EXAFS study of the structural properties of In and In + C implanted Ge [PDF]

, 2021
The structural configurations of In implanted Ge have been studied via x-ray absorption spectroscopy with and without the codoping of C. In the case of In singly implanted Ge, while the In atoms occupy an substitutional site in Ge (InGe4) at low In ...
