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.

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

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.
