Abstract

We have measured and calculated the intensity profiles for S 2p photoemission at 1327 eV from the well-defined adsorbate system, c(2 × 2)S on Ni(001), and have analyzed these via several holographic imaging procedures. Images of nearest-neighbor S atoms are clearly seen in both experiment and theory, and their positions are improved if effects due to twin images are suppressed by analyzing only a half hologram. Image positions are further improved to within ± 0.2-0.3 Å with corrections for scattered-wave amplitudes and phase shifts.
