Thanks. While none of these have to do with pre-edge peaks such as are found in transition-metal oxides, the assumption of constancy of core-hole broadening does seem to work. mam ----- Original Message ----- From: Iztok Arčon To: XAFS Analysis using Ifeffit Sent: Monday, October 10, 2011 12:32 AM Subject: Re: [Ifeffit] lifetime broadening of pre-edge peaks? Dear Matthew you can find examples of determination of life-time broadening, deconvolution of XANES specra, and discussion about limitations due to noise in several papers, for example: A. Filipponi, J. Phys. B 33, 2835 (2000) A. Kodre, I. Arčon, J. Padeznik Gomilšek, R. Frahm J. Phys. B: At. Mol. Opt. Phys. 35 (2002) 3497-3513 A. Kodre, J. Padežnik Gomilšek, A. Mihelič, I. Arcon Radiation Physics and Chemistry 75 (2006) 188-194 J. Padeznik Gomilsek, I. Arcon, S. de Panfilis, A. Kodre, Phys. Rev. A 79, (2009) 032514, regards Iztok Matthew Marcus wrote: Is the core-hole lifetime broadening of pre-edge XANES peaks the same as at the main edge? I'm looking into issues of de-noising of XANES epsctra, so need to figure out how narrow real features can be. mam _______________________________________________ Ifeffit mailing list Ifeffit@millenia.cars.aps.anl.gov http://millenia.cars.aps.anl.gov/mailman/listinfo/ifeffit -- prof. dr.
