We demonstrate holographic reconstruction using low-energy electron-diffraction (LEED) and low-energy positron-diffraction (LEPD) intensity spectra. Calculated LEED and LEPD intensity spectra from a multiple-scattering method are inverted to produce high-fidelity images of near-neighbor atoms whose positions are measured from an adatom. We show that low-energy positron diffraction is better suited for holographic reconstruction because positron scattering in solids is weaker than that of electrons.
