The effect of large hydrogen concentrations (\ensuremath{\approx}30% atomic), on the superconducting transition temperature ${T}_{c}$ of Nb films is discussed. The hydrogen is incorporated in solutionlike phases which occur at these concentrations be

X-ray absorption near-edge structure (XANES) measurements were used to probe the H-charging-induced electronic structure changes of a 2400 \AA{} Nb film capped with Pd. These results are discussed in terms of ab initio linear augmented plane-wave (LA

Hydrogen uptake and discharge by thin metallic films under potentiostatic control was studied using x-ray diffraction at the National Synchrotron Light Source (NSLS). The formation of metal-hydrogen phases in Pd, Pd-capped Nb and Pd/Nb multilayer ele

We present in situ neutron-reflectivity measurements of the hydrogen and deuterium absorption from the gas phase in a Pd/Nb/Pd thin film multilayer. Hydrogen and deuterium were both preferentially absorbed into the Nb layer at room temperature and at

Photoelectron spectra were used to characterize the oxidation of thin aluminum films on Ta(110). The exposure of bare Ta(110) to langmuir amounts of O 2 generates Ta 4f spectral components related to chemisorbed atomic oxygen and a thin oxide layer.

Photodesorption of gas, particularly H2, by synchrotron radiation in the proposed next generation of superconducting proton colliders is a critical issue confronting the design of the vacuum system. As an initial step in understanding the source of t

Photoelectron spectroscopy is used to study the interaction of H2O with GaAs(100) at 90 K and to assess its use as a photon‐assisted oxidizing agent. The condensation of H2O at 90 K produces a thin physisorbed layer on GaAs(100). We found that inte

The interface formation of Cr/NH3/GaAs(100) and its temperature dependence using synchrotron radiation photoemission and resonance photoemission spectroscopies have been investigated. We observed that at T=90 K the initial deposition of Cr stimulated

Photoemission is used to examine valence electronic structure of Yb deposited on condensed ammonia or xenon films. The deposition of Yb onto solid ammonia produces a Yb phase whose two 4[ital f] peaks lie at a higher binding energy than Yb metal and
