In this paper, we employ new technique by use of an analytical electron microscope to determine occupation probabilities of atoms on the crystal lattice sites in multi-component ordering alloys. This technique consists of two measurements by Intersecting Kikuchi-line (IKL) method and ALCHEMI (Atom Location by Channelling Enhanced Microanalysis). The application of this new technique to (CuAu)85Pd15 ternary alloy with Ll0-type order structure is demonstrated. The occupation probabilities of constituent atoms on the crystal lattice sites have been given by these measurements. It was revealed from these results that the ordering interaction occurs between Cuand Au atoms, or Cu and Pd atoms and that the interaction between Cu and Pd is stronger than that between Cu and Au.
