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 ------------------------- Gerald T.

If so, what programs are you using for this purpose? Any hint would be of great help With many thanks and best wishes Jakob
