Abstract
A low-energy electron diffraction (LEED) study of at 77 K indicates that the Xe adsorption site is on top of the Pd atoms. The Xe–Pd bond length is The substrate structure is essentially unrelaxed from the bulk structure. These results contrast with an earlier spin-polarized LEED study, which indicated that hollow sites are occupied in this structure. The low-coordination-site geometry for Xe on Pd(111) is discussed in the context of earlier experimental studies and recent density functional theory results for Xe adsorption on metal surfaces.
