A multiparameter scheme of determining geometric characteristics and constructing empirical muffin‐tin potential for nonmetallic crystals by using XANES data is proposed. It is based on the S ‐matrix pole equation for many‐centre systems. Input data are energies and halfwidths of spectral maxima of the one‐electron origin. The scheme is tested by determining the lattice parameter of KCl.
