	abstract = {The KLL Auger electron spectra of Zr (Z = 40) and Nb (Z = 41) following respectively the electron capture (EC) decay of 90Nb and the de-excitation of the isomeric state of 91mNb were investigated in detail using a combined electrostatic electron spectrometer and radioactive sources prepared by surface sorption on a polycrystalline carbon substrate. For both elements, energies, relative intensities, and natural widths of all the nine well-resolved basic spectrum components were determined and compared with theoretical predictions and with results of previous measurement as well. Results of our ab initio multiconfiguration Dirac-Hartree-Fock calculations are discussed also in relation to the solid-state effect. Indications of an influence of the EC decay on the absolute energy of the KL2L3(1D2) transition (so-called atomic structure effect) in Zr were found. The effect of the retarded current-current interaction on the KL1L2(3P0) transition intensity was observed to be appreciable for the investigated elements in accordance with the prediction.},

	abstract = {A film of niobium (similar to 15 A thick) deposited under ultrahigh vacuum (UHV) conditions on polycrystalline zirconium was studied by x-ray photoelectron spectroscopy (XPS) as it was taken through a series of sequential treatments. The Nb-Zr interface, associated with a Nb 3d(5/2) peak at 203.4 eV, is indicated to passivate the underlying Zr to oxygen and hydrogen plasma treatments, which in the absence of Nb would yield substantial oxidation. On heating to 500 degrees C, the pure metallic Nb 3d(5/2) component at 202.2 eV appears, and this change is accompanied by removal of the passivation effect on the substrate.},

	abstract = {The interaction of a film of Zr (similar to 38 Angstrom thick) deposited under ultrahigh vacuum (UHV) on to an approximately 12 Angstrom film of NbO on a gold substrate has been studied with X-ray photoelectron spectroscopy (XPS). Evidence is presented for an interfacial conversion from Zr and NbO to ZrO2 and Nb. The reactivity of this sample was studied through a series of sequential treatments. Although changes occur in the topmost layer, the Zr/Nb interfacial region, as identified by a shoulder at similar to 180 eV in Zr 3d and the 203.0 eV peak in Nb 3d, appears to be remarkably inert on heating at 300 degrees C under UHV, as well as on subjecting to O-2 and hydrogen plasma treatments.},

	abstract = {X-ray photoelectron spectroscopy (XPS) has been used to study the interfacial chemistries of a 65-Angstrom film prepared by depositing zirconium in an oxidizing environment onto a methane-pretreated 11-Angstrom thick zirconium oxide film, which initially was deposited onto a gold substrate. The second metal deposition results in an outermost region composed of a mixed zirconium oxide, while below there is metallic zirconium followed by zirconium carbide and carbon on top of the first zirconium oxide film, which is itself in contact with the gold. The carbide component showed no changes on heating to 425 degrees C, on treating with a hydrogen plasma at room temperature, or on heating the resulting film to 425 degrees C. The oxide layers do show characteristic changes, and this also contrasts with earlier observations for a zirconium sulphide film. The zirconium carbide Zr3d(5/2) component has a binding energy of 180.6 eV.},

	abstract = {X-ray photoelectron spectroscopy (XPS) has been used to characterize thin films formed by the deposition of zirconium on to gold foil. With deposition rates of the order of 1 angstrom min-1, in the presence of an atmosphere of 10(-9) mbar H2O, the film has an outer region Of ZrO2 and inner regions of a lower oxidation state material, ZrO(x), and Zr-Au alloy. Initially both ZrO(x) and Zr-Au alloy are oxidized by either H2O or O2 at 300-degrees-C, although this process is hindered as the ZrO2 layer gets thicker. However, even with the protective oxide layer, heating in 5 x 10(-7) mbar D2 (with a partial pressure of 10(-9) mbar H2O) can convert ZrO(x) to ZrO2, a reaction apparently facilitated by migrating D atoms.},
