Abstract
We develop a procedure to interpret the model Mössbauer spectra (MS) of resonant nuclei in a two-component crystal with short-range order. The procedure is describable not only by pair correlations but also by multiparticle correlations of the atomic distribution. The results of the interpretation are used to find Mössbauer parameters for subspectra and for certain correlation moments that describe the short-range order. The developed approach was used to interpret the actual spectra of 57Fe in iron-chromium alloys.
