[Ifeffit] Deconvolution of XANES spectra

[Gerald Seidler]

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

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
