A radial atomic distribution study of the amorphous alloy Ge0.20Bi0.06Se0.74 was performed from the X-ray diffraction data of the samples obtained by quenching the molten material. Short-range order information was obtained by interpreting the Radial Distribution Function data, using a theoretical expression which takes into account the variation of the atomic scattering factors with s (the scattering vector module) and approximates them to polynomic functions. The tri- and tetra-coordinated germanium hypotheses, suggested in the literature for glassy alloys containing this element, were found to be compatible with the experimentally obtained structural information. Spatial atomic distribution models were generated, considering the coordination hypotheses suggested for the germanium, using the adequately modified Metropolis-Monte Carlo method. A comparative analysis of the structural parameters of these models showed good agreement with the values given in the literature for similar alloys.
