Abstract
A problem of core level width deconvolution in EXAFS spectra is discus sed. A method has been developed which allows a correction of experime ntal spectra. A special iterative algorithm of solving the integral eq uation has been proposed. The method has several advantages over other previous ones such as a high stability to statistical noise, a good c onvergence. Model numerical experiments have been carried out. An EXAF S spectrum of polycrystalline Pd with a core level width Gamma = 6.1 e V is presented as an example where the broadening effect is essential.
