The basic XAFS equation given by Sayers, Stern and Lytle is solved by a linear inverse problem method instead of usual Fourier transform. The Wavelet-Galerkin discretization is utilized in our formulation for efficient calculations. As a result of model calculations, sufficiently exact solutions for radial distribution function are obtained with expansion by a small number of wavelets within the range of description of the basic XAFS equation.
