Abstract
A new method of determining partial interatomic distances in multicomponent systems from extended X-ray absorption fine structure data is presented. The method is based upon the regular procedure of solving a Fredholm integral equation of the first kind. The effectiveness of the method has been tested on mode1 examples of two closely spaced coordination spheres and crystalline CuZr2. The partial interatomic distances of amorphous Cu33Zr67 have been investigated by EXAFS using the synchrotron radiation of a VEPP-4 storage ring. The structural results are compared with previous experimental and theoretical investigations.
