EMPIRICAL N-BODY POTENTIAL FOR CUBIC METALS

Many-body empirical model potentials are formulated in tile frame of t he embedded-atom method (EAM) of Daw and Baskes for homonuclear cubic metals. The basic functions of the model (the pair interaction potenti al electron density function, and embedding energy function) are prese nted in analytical forms which do not impose limitations at least on t he basic properties of the system like Cauchy discrepancy, equal aniso tropy ratio imposed by the Johnson's EAM potential, etc. The developed potentials are convenient for computer simulations.
