X-ray atomic properties of nickel were investigated in a singular approach that combines different experimental techniques to obtain new and useful reliable values fundamental parameters for spectrometric purposes comparison theoretical predictions.We determined the mass attenuation coefficients an energy range covering L-and K-absorption edges, K-shell fluorescence yield Kβ/Kα Kβ 1,3/K α1,2 transition probability ratios.The obtained line profiles linewidths Kα transitions Ni can be...
We have investigated systematically the $K\ensuremath{\alpha}$ x-ray spectra in elements from Ca to Ge within Berger's two-Lorentzian functions model, using a high-resolution antiparallel double-crystal spectrometer, order obtain detail physical meaning of asymmetry spectral profiles. The overall tendency corrected full width at half maximum $K{\ensuremath{\alpha}}_{1}$ and $K{\ensuremath{\alpha}}_{2}$ lines as function $Z$, well linewidths, are good agreement with data reported literature....
The $K\ensuremath{\beta}$ x-ray spectra of the elements from Ca to Ge have been systematically investigated using a high-resolution antiparallel double-crystal spectrometer. Each $K{\ensuremath{\beta}}_{1,3}$ natural linewidth has corrected instrumental function this type spectrometer, and spin doublet energies obtained peak position values in spectra. For all studied $K{\ensuremath{\beta}}_{1}$ lines FWHM increase linearly as $Z$. However, for $K{\ensuremath{\beta}}_{3}$ dependence is...
The core-level x-ray photoemission spectroscopy (XPS) satellites of single-crystalline ${\mathrm{SrTiO}}_{3},$ ${\mathrm{SrTiO}}_{3}:\mathrm{La},$ and ${\mathrm{SrTiO}}_{3}:\mathrm{Nb}$ in situ fractured ultrahigh vacuum were compared with the electron-energy-loss spectrum theoretical functions from first-principles electronic structure calculations. Experimental XPS O $1s$ can be represented by peaks positioned at 6.1, 11.7, 14.2, 17.2, 19.7, 27.4, 30.6 eV. prominent features agreed those...
A simulation of pulsed photoacoustic signals using the finite elements method is demonstrated, a hypothetical cylindrical brass sample surrounded by air, and weak energy density laser source to prevent from being destroyed. Both distribution temperature also thermal deformation stress in are discussed.
We compare experimental $\mathrm{O} 1s$ electron energy-loss structures below 30 eV of single crystalline ${\mathrm{SrTiO}}_{3},$ ${\mathrm{BaTiO}}_{3},$ and ${\mathrm{TiO}}_{2}$ with their theoretical functions. The photoelectron in situ fractured surface ultrahigh vacuum can be approximated by a sum four components for ${\mathrm{SrTiO}}_{3}$ three ${\mathrm{TiO}}_{2}.$ Electronic were calculated from first principles using the full-potential linearized augmented plane-wave method...
We report experimental energy-loss structures in x-ray photoemission spectra of single crystalline ${\mathrm{LiTaO}}_{3}$ and ${\mathrm{LiNbO}}_{3}$, then compare these with theoretical electron-energy-loss functions calculated from first principles using the full-potential linearized augmented plane-wave method local-density approximation. The structure core electrons can be approximated by a sum four components: for ${\mathrm{LiTaO}}_{3},$ peaks positioned at 8.0, 13.4, 15.8, 22.6 eV;...
X-ray absorption fine structure combined with fluorescence spectrometry was applied to various V+TiO2 hybrid samples. Emitted V K alpha1 from the sample selectively counted by using a high-energy-resolution (0.4 eV) spectrometer equipped Ge(331) crystal. Two advantages of this method, extremely high signal/background ratio and compatibility measurements in atmosphere reaction gas (in situ study relation heterogeneous catalysis), were effective at K-edge. Structure transformation sites...
An investigation of Cu Kα X-ray emission spectra, together with their satellite lines, using both experimental techniques and theoretical calculations, provides accurate values for the natural linewidths other parameters lines.
For Na-free and Cu-deficient CuInS2 thin films with chalcopyrite structure, electron spectra of core levels valence band were similar to each other in spite a difference Cu deficiency. Incorporation Na the caused peak shifts by −0.5 eV for without changes both linewidth shape. The density states, deeper 1–5 than that from d–S p hybridization centered at around 2.5 eV, increased incorporation, increments states larger incorporation yielded surface layer expressed as (Na,Cu)InS2 on deficient films.
A large enhancement of critical current density with the small rate flux creep was realized by x-ray irradiation before oxygen annealing for Gd1Ba2Cu3O7−x superconducting thin films. The significantly increased magnetization showed both temperature independence and magnetic relaxation. activation energy estimated model from 0.1 to 0.25 eV treatment.
The Ti $K{\ensuremath{\alpha}}^{\ensuremath{''}}$ satellite is investigated using a Johann-type spectrometer on the BL15XU undulator beam line of SPring-8 at excitation energies between 4996 and $7000\phantom{\rule{0.3em}{0ex}}\text{eV}$. intensity relative to that $K{\ensuremath{\alpha}}_{1,2}$ exhibits an abrupt jump from $0%$ $\ensuremath{\sim}1%$ in range $10\phantom{\rule{0.3em}{0ex}}\text{eV}$ around energy $5010\phantom{\rule{0.3em}{0ex}}\text{eV}$. reach saturation...
