Abstract
Epitaxial Ce layers have been obtained by evaporation on a V(110) surface. The Ce phase reported some years ago for this system is not confirmed in our experiments: the analysis of reflection high-energy electron-diffraction and x-ray-photoemission data leads us to identify the epitaxial Ce phase with a Ce-γ phase. Under several circumstances, epitaxy of Ce oxides has been observed on V(110): in these cases, the epitaxial surface lattice is found to be hexagonal with a parameter =3.9±0.1 Å, and does not depend (in the limit of experimental errors) on the amount of oxygen.
