摘要
Low-energy electron diffraction (LEED) studies of Pt(111)-(root 3 x root 3)R30 degrees-Xe at 80 K and 110 K indicate that the Xe adsorption site is on top of the Pt atoms with a Xe-Pt distance of 3.4 Angstrom. The substrate structure is essentially unrelaxed with respect to die bulk. 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 is discussed in the context of earlier studies of Xe adsorption. [S0163-1829(99)03939-9].
