	abstract = {The re-analysis with LEED for the Pd(1 0 0)-(root5 x root5)R27 degrees -O surface structure confirms the basic model, reported previously by Vu et al. [Surf. Sci. 318 (1994) 129], in which a PdO(0 0 1) overlayer is stacked on to the Pd(1 0 0) surface. The refinement reduces the Pendry R-factor to 0.306, from 0.44 in the earlier study, and the detailed structure at the metal-oxide interface shows evidence for a balancing of interactions compared with requirements for the oxide and metal separately. Pd atoms in the oxide layer have a corrugation estimated at 0.20 Angstrom, and the binding of this layer to the metal induces a substantial rumpling in the interface region, which covers especially the first and second metallic layers with corrugations of 0.45 and 0.15 Angstrom respectively.

	abstract = {A recent communication [11] reported a novel structure for the (root 7 x root 7)R19.1 degrees reconstruction formed by P on the Rh(111) surface, and the present paper details the associated tensor LEED analysis. This reconstruction involves a packed arrangement of Rh pentagons and triangles for the topmost layer, with P atoms at 3/7 monolayer coverage occupying eight-coordinate sites created by the Rh pentagons. The nearly flat, densely packed Rh-P mixed layer (density of five Rh and three P atoms per seven Rh atoms in the substrate unit mesh) appears to provide a major stabilizing effect on this surface. The average P-Rh bond distance is indicated to be 2.52 Angstrom, slightly longer than that (2.38 A) in bulk Rh2P where the P atoms are also eight-coordinate. Some similarities are noted with the corresponding (rv (7) over bar x root 7)R19.1 degrees structures formed by S on the Pd(111), Cu(111) and Ag(111) surfaces.},

	abstract = {LEED crystallographic analyses have been made for two structures formed by the (0001) surface of zirconium and which show (1 x 1)-type diffraction patterns. An analysis with eight diffracted beams for clean Zr(0001) supports an earlier conclusion that this surface has a regular hcp-type structure, and that the first interlayer spacing shows a contraction hem the bulk spacing by about 1.6\%. A surface formed by O, at twice the coverage applying for the best-developed half-monolayer (2x2) diffraction pattern, is analyzed using tensor LEED for nine diffracted beams, including the use of the average t-matrix approximation. It is concluded that the 1 monolayer (ML) structure is actually disordered with 0.5 ML of O distributed statistically over octahedral holes between the first and second Zr layers, and another 0.5 ML of O similarily distributed between the second and third metal layers.},

	abstract = {A tenser LEED analysis has been made for the Cu(110)-c(6 x 2)-O surface structure using intensity versus energy curves measured for 13 diffracted beams at normal incidence. A good level of correspondence between experimental and calculated intensities has been reached (R(p) = 0.271) for the model type (2/3 monolayer coverage of O) proposed for this surface by Feidenhans{\textquoteright}l et al. This analysis provides direct information on the structural details, and it is indicated that they support the view that the driving force for this structure relates to sufficient O being incorporated in order to stabilize the surface as a modified (211) plane of bulk Cu2O. This structure is composed of double-stranded chains built from 12-membered rings formed by alternating O and Cu atoms. The chains are flattened on the surface, and alternating chains are laterally displaced by half a repeat unit compared with the bulk (211) plane. However, the three-atom O-Cu-O fragments essentially maintain their bulk form in the surface structure. The average O-Cu bond length in Cu(110)-c(6 X 2)-O is indicated to equal 1.90 Angstrom, in exact agreement with the values determined for the half monolayer structures formed by O on Cu(110) and Cu(100).},

	abstract = {A tensor LEED analysis for the Rh(110)-(3 x 2)-S surface supports an arrangement of chemisorbed S atoms at 2/3 monolayer coverage on a basically unreconstructed metallic structure. Alternating [1(1) over bar0$] channels in the metal surface are occupied differently, although each has two S atoms per unit mesh. In one set, the S atoms occupy long-bridge and centre sites with a constant separation along the channel of 4.03 Angstrom. In the other set of channels, all S atoms occupy equivalent positions, displaced from regular centre sites by 0.39 Angstrom, to give successive S to S separations of 3.47 and 4.60 Angstrom. The long-bridge site bonding is a novel feature which is facilitated by the neighbouring topmost Rh atoms relaxing laterally by about 0.27 Angstrom perpendicular to the [1(1) over bar0$] row. Bucklings of 0.20 and 0.10 Angstrom are indicated to occur in the first and second Rh layers respectively; the latter value essentially equals that (0.11 Angstrom) reported earlier for the corresponding half monolayer c(2 x 2) surface. For S atoms at or near centre sites in the (3 x 2) structure, the average S-Rh bond distances are 2.42 and 2.29 Angstrom to the first and second layer Rh atoms respectively; the corresponding values at the long-bridge sites are 2.20 and 2.27 Angstrom.},
