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.
