The scattering wave (SW) method is generalized for the case of Hartree‐Foek atomic potentials in ionic crystals. An earlier developed scheme of these crystal potential construction is used to obtain photoelectron scattering phase shifts. X‐ray absorption near edge structure (XANES) and extended fine structure (EXAFS) of crystals NaCl, KCl, NaF are then calculated in the single‐ scattering approximation of the SW‐method. The approach used permits to obtain EXAFS of ionic crystals with high accuracy and also the main features of their XANES.
