We have performed a quantitative structure determination of the ffiffiffi 5 p ffiffiffi 5 p R27 surface oxide, formed on Pd(100) under semi-realistic conditions for catalytic CO oxidation, using in situ high-energy surface X-ray diffraction. We describe the experiment and the extraction of quantitative data in detail. The structural results are in agreement with previous reports of a system consisting of a single layer of PdO(101) formed in pure O 2 on top of Pd(100) and studied under
