Hi Matthew,
The lifetime broadening of the XANES features is determined by the time of life
of the final excited state. This two-particle excitation includes the core hole
and the photoelectron. The core hole may decay due to the various radiation or
non radiation processes. The photoelectro

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:

I'm sure
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)

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.
