The anomalous wide angle X-ray scattering technique was used to determine the partial structure factors and then the partial radial distribution functions for vacuum evaporated Cd-As amorphous films containing 41 and 74% at. As. The experiments were performed using synchrotron radiation tuned near the As and Cd absorption edges. The obtained structural information about the individual Cd-Cd, Cd-As and As-As correlations shows that As and Cd remain almost tetrahedrally coordinated and suggest a certain degree of chemical disorder of the investigated samples.
