Dear Jakob,
Attached you will find my student's recent paper on deconvolution of
XANES and EXAFS using iterative maximum-likelihood algorithms (TT Fister
et al, Phys Rev B vol75, artNo.174106 ). Our software is available
through EPAPS, but it is in Mathematica, which I realize isn't most
convenient for many users.
We will have matlab/scilab versions ready by the end of the summer which
will include both the Richardson-Lucy (ratio) method from our paper and
also the deCittert (linear) method previously used with good success by
Babanov. The matlab/scilab package will come with a GUI so that it
should be easy to use, even for experimenters with no knowledge of those
programming environments. After that, we'll start working on making a
stand-alone executable... but note that scilab is free (it is the
shareware copy of matlab).
Let me know if you'd like to talk about your particular application. We
have a pretty good idea about the likely performance of our approach for
different spectra, and I would be happy to run some test deconvolutions
for you.
Cheers,
Jerry

Subject: [Ifeffit] Deconvolution of XANES spectra
Dear all,
I would like to know whether some of you do have experience in
deconvoluting XANES spectra in order to remove both, lifetime and
experimental broadening. If so, what programs are you using for this
purpose?
Any hint would be of great help
With many thanks and best wishes
Jakob
