Abstract
It is shown that the full scattering matrix associated with an assembly of nonoverlapping potentials of arbitrary convex shape has precisely the same form as the corresponding expression for potentials confined inside nonoverlapping spheres. A specific implication of this result is that the electronic structure of periodic solids can be obtained from the solutions of a secular equation formally identical to that of the Korringa-Kohn-Rostoker method for periodic muffin-tin potentials.Keywords
