Abstract
Neon diffraction from dense metal surfaces is reported for the first time. Contrary to expectation, pronounced rainbow scattering at angles of ∼ 12° for Ni(110) and ∼ 40° for Pd(110) shows that the corrugation amplitudes are much larger for Ne than for He. This opens important extensions for atomic-beam studies of surface structure and composition and, as Ne is also more sensitive to dilute adsorbates, of surface defects and migration.Keywords
