We have measured high-energy-resolution Fe 2p photoelectron spectra for ?-Fe2O3/?-Al2O3(0001) grown by oxygen-plasma-assisted molecular beam epitaxy at emission angles chosen to enhance bulk and surface contributions. We quantitatively reproduce the subtle lineshape differences in these spectra by taking into account the break in symmetry and change in crystal field splitting generated by the presence of the surface.
