Abstract

XAFS spectra near K absorption edges of Pt (78.4 keV) and Pb (88.0keV) were measured in transmission mode with Si (511) planes of an adjustable inclined double-crystal monochromator at bending-magnet beamline BL01B1 at SPring-8. The energy resolution was estimated as good as 7 eVat Pt K-edge, benefitted from the high brilliant x-rays from the SPring-8 storage ring. Blunt edge jumps and reduction of EXAFS amplitude were observed owing to the finite lifetime of the core hole as predicted theoretically. Local structure parameters have been successfully evaluated from EXAFS signal above the K edge.
