Phys. Rev. Lett. 69, 3654–3657 (1992)Low-energy electron and low-energy positron holographyReceived 11 June 1992; published in the issue dated 21 December 1992 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. © 1992 The American Physical Society URL:
