Abstract Angle-resolved mass spectroscopy of recoiled ions data was obtained for the CeO{sub 2}(001) surface. Prior theoretical investigations have suggested that the (1{times}1) unreconstructed surface, terminated with bulk equivalent layers of either cerium or oxygen, is unstable due to a nonzero surface dipole. In this investigation, it was experimentally determined that the surface is terminated with 0.5 monolayers of oxygen. This model results in a stable surface with a zero dipole moment. {copyright} {ital 1999} {ital The American Physical Society}
