    "abstract": "A Bayesian method application to the deconvolution of EXAFS spectra is\nconsidered. It is shown that for purposes of EXAFS spectroscopy, from the\ninfinitely large number of Bayesian solutions it is possible to determine an\noptimal range of solutions, any one from which is appropriate. Since this\nremoves the requirement for the uniqueness of solution, it becomes possible to\nexclude the instrumental broadening and the lifetime broadening from EXAFS\nspectra. In addition, we propose several approaches to the determination of\noptimal Bayesian regularization parameter. The Bayesian deconvolution is\ncompared with the deconvolution which uses the Fourier transform and optimal\nWiener filtering. It is shown that XPS spectra could be in principle used for\nextraction of a one-electron absorptance. The amplitude correction factors\nobtained after deconvolution are considered and discussed.",
