A Unified Approach to Various Lattice Models BY J. 0. A. IDIODI This work proposes the separable potential method (SPM) as a unified treatment of a class of lattice models. The richness in structure of the unified approach is demonstrated through contact with some of the most important lattice models in the literature, the embedded-atom method (EAM) being one of such models. As a practical application of SPM some fairly extensive results for f.c.c. metallic copper are reported.Ce travail propose le ((separable potential method (SPM))) pour le traitement unifie d'une classe des modeles lattice. La richesse en structure de cette approche est mise en evidence en comparant avec des modeles les plus importants trouves dans la litterature tel que I' ((embedded atom method (EAM),).
