Low energy ion scattering with the use of a neutral He0 beam (NBISS) has been applied to analyze the structure of MgO(001) with Ca2+ impurities segregated from the bulk. The NBISS technique successfully avoids specimen charging, which is a common obstacle to analyzing the insulating surface by using ordinary ion scattering techniques. It is found that the segregated Ca2+ ions are substituted for the Mg2+ ions at the surface and are protruding from the original MgO plane by 0.4±0.1 Å.
