dc.description.abstractIf the range of XANES spectra varies between sets of scans, it may be impossible to compare sets of spectra unless a restricted part of the spectra is used. The paper derives a decision process for comparison of partial and complete XANES spectra, taking lead as an example. Lead L3-edge XANES spectra were collected at the Australian National Beamline Facility (BL-20B) Photon Factory, Tsukuba, Japan over the energy range 13,000-13,150 eV (ring conditions: 2.5 GeV, 300-400 mA). The monochromator step size was reduced to 0.25 eV per step in the XANES region (13,000-13,100 eV and 13,040-13,100 eV) to collect high-resolution spectra. XANES data for samples and model compounds were collected at ambient temperature and pressure in fluorescence, using simultaneous collection of a Pb metal reference foil for energy calibration (first derivative peak of elemental Pb was 13,050 eV). XANES spectra were fitted using spectral deconvolution and least-squares linear combination fitting (LCF). Detailed XANES results with LCF approach over various energy ranges are illustrated and discussed and show the applicability of the decision-making procedure to compare sets of spectra. © 2010 American Institute of Physics.
