Scanned-energy mode photoelectron diffraction (PhD), using the O 1s and V 2p\ud photoemission signals, together with multiple-scattering simulations, have been used to\ud investigate the structure of the V2O3(0001) surface. The results support a strongly-relaxed\ud half-metal termination of the bulk, similar to that found in earlier studies of Al2O3(0001)\ud and Cr2O3(0001) surfaces based on low energy electron and surface X-ray diffraction\ud methods. However, the PhD investigation fails to provide definitive evidence for the\ud presence or absence of surface vanadyl (V=O) species associated with atop O atoms on\ud the surface layer of V atoms. Specifically, the best-fit structure does not include these\ud vanadyl species, although an alternative model with similar relaxations but including\ud vanadyl O atoms yields a reliability-factor within the variance of that of the best-fit\ud structure
