Abstract
The technique of holographic image reconstruction based on photoelectr on detection has been applied to the Pb/Si(111)-(root 3 X root 3)R30 d egrees-beta phase for a determination of the surface structure. Angle- resolved photoemission from the Pb5d core level shows intensity oscill ations as a function of photon energy. These constant-initial-state sp ectra were taken at various emission angles and Fourier inverted to yi eld three-dimensional real-space images of the nearest neighbors to th e emitter atom. These images clearly show Pb atoms adsorbed at the T-4 , site.
