Reexamination of Scattering by a Pair of Fixed Dipolar Charges

Abstract

Upon careful examination of charged-particle scattering by a finite stationary dipolar system, it is found that the long-range nature of the dipole potential leads to divergence of the total scattering cross section. Thus, contrary to the results of Takanagi and Itikawa, the total cross sections for the finite dipole diverge in a manner similar to that found earlier by Mittleman and von Holdt for the point dipolar field.
