摘要：

A low-energy electron diffraction (LEED) study of Pd(111)-(root3xroot3)R30degrees-Xe at 77 K indicates that the Xe adsorption site is on top of the Pd atoms. The Xe-Pd bond length is 3.07 Angstrom+/-0.06 Angstrom. 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.
