Correcting an experimental absorption spectrum for the core level width

The problem of correcting EXAFS spectra by the core level width is discusse d. A method of correcting experimental EXAFS spectra is developed. An itera tion algorithm for solving the integral equation is proposed. This method h as a number of advantages over other methods, namely, high stability agains t statistical error and fast convergence. Model numerical calculations are performed. An example is the EXAFS spectrum of polycrystalline Pd for which the broadening effect is significant.
