A Green's function calculation is presented for dilute concentration isovalent substitutional defects in alkali halides. A simple model is suggested to extend this calculation to the high concentration range. Comparing the values of lattice relaxation obtained from this estimation to EXAFS measurement, a very good agreement is noticed over the entire composition range.
