VALIDITY AND ACCURACY OF MULTIPLE-SCATTERING THEORY

According to a recent paper by Badralexe and Freeman [Phys. Rev. B 37, 10 469 (1988)] multiple-scattering theory (MST) and Korringa-Kohn-Rostoker (KKR) theory do not yield correct solutions to the wave equation. Here, an attempt is made to evaluate this claim by searching for errors in the MST and KKR equations using one- and two-dimensional models. No evidence is found to support the Badralexe-Freeman claim. © 1990 The American Physical Society.
