Abstract
A generalization of the box-variational method is developed to describe particle scattering with the Dirac equation. The method is applied to extract phase shifts from all-order single + double relativistic many-body perturbation theory calculations of the electron-helium, electron-neon, and electron-krypton systems. Comparisons with experimental elastic and momentum transfer cross sections are made. Agreement at the to level is achieved for helium and neon. The scattering length for krypton is smaller in magnitude than experimental estimates derived from swarm experiments.
