Low Energy Photoelectron Diffraction at High Angular Resolution as a Surface Structure Probe

The EDAC multiple scattering computer package has been used to simulate X-ray photoelectron diffraction experiments of Cu(100) surfaces at kinetic energies of 303.5 eV and below. At 1 angular resolution EDAC produces visually distinct patterns for bulk truncated Cu(100) and buckled Cu(100) surfaces with and without an Mn overlayer. Changes to Cu(100) surface relaxation parameters have discernable effects at kinetic energies of ~100eV.
