A CONSISTENT FORMALISM FOR PARTIAL STRUCTURE FUNCTIONS

The structure of an amorphous binary system can be described by three partial structure functions and their Fourier transforms relating to t he atomic interactions. The experimental total function is the weighte d sum of the partials. Two different formalisms, the Faber-Ziman and A shcroft-Langreth, are generally applied for expressing the weights. Th is paper suggests a third formalism, created by taking into considerat ion the physically established features of both of the other formalism s. It is free from the difficulties that may arise when these formalis ms are used.
