Optical potential calculation of elastic electron scattering from heavy noble gases

We have developed a complex optical potential within the framework of the Dirac equations to account for the absorption of flux into the inelastic channels for electron scattering at intermediate energies. We have used Dirac-Fock wave functions to represent the fine-structure excited states of the atomic target. Detailed results will be given for elastic scattering from argon, krypton and xenon.
