Abstract

We have previously published a non-relativistic generalization of the non-perturbative polarized-orbital method which can be used to calculate long range polarization potentials for electron and positron scattering from atomic systems. Here we present a relativistic version of this method which is designed for heavy atomic systems with large polarizabilities such as caesium or the excited states of xenon. The detailed formulae are based upon the representation of atomic states by Dirac-Fock wavefunctions.
