“…They determined the energy of the 1s → 1π * transition at 530.8 eV with a stated accuracy of ±200 meV. By measuring the ion yield in a gas cell, Coreno and co-workers [34] improved the accuracy for this line to ±100 meV by normalization on the 1s → 1π * transition EELS measurements, both for O 2 [33] and CO [35], the latter being quoted to an accuracy of ±90 meV. To double-check this determination independently of the relatively low-resolution EELS measurements, we used a Scienta electron spectrometer installed on a second branch of the PLEIADES beam line.…”

Absolute cross sections for the single and double K-shell photoionization of carbonlike O 2+ and nitrogenlike O + ions were measured in the 526-620-eV photon energy range by employing the ion-photon merged-beam technique at the SOLEIL synchrotron radiation facility. High-resolution spectroscopy up to E/ E ≈ 5300 was achieved. Rich resonance structures observed in the experimental spectra are analyzed and identified with the aid of R-matrix and multiconfiguration Dirac-Fock (MCDF) methods. For these two atomic oxygen ions of particular astrophysical interest we characterized the strong 1s → 2p and the weaker 1s → np (n > 2) resonances observed. A detailed comparison of the energies of the 1s → 2p resonances in the first members of the oxygen isonuclear sequence measured by synchrotron based experiments and the Chandra and XMM-Newton x-ray satellites is presented.

“…The C 1s and O 1s spectra were calibrated using the C 1s f π* transition of CO (287.40 eV) 23 and the O 1s f π* transition of CO (534.20 eV). 24 The Si 2p/2s spectra were calibrated with respect to the C 1s spectra of each species.…”

The C 1s, Si 2p, Si 2s, and O 1s inner-shell excitation spectra of vinyltriethoxysilane, trimethylethoxysilane, and vinyltriacetoxysilane have been recorded by electron energy loss spectroscopy under scattering conditions dominated by electric dipole transitions. The spectra are converted to absolute optical oscillator strength scales and interpreted with the aid of ab initio calculations of the inner-shell excitation spectra of model compounds. Electron energy loss spectra recorded in a transmission electron microscope on partly cured adhesion promoter, atomic force micrographs, and images and X-ray absorption spectra from X-ray photoemission electron microscopy of as-spun and cured vinyltriacetoxysilane-based adhesion promoter films on silicon are presented. The use of these measurements in assisting chemistry studies of adhesion promoters for electronics applications is discussed.

“…To find precise energy positions for the mentioned structures, we routinely measure and calibrate them against well defined ionization lines of N 2 in all available orders up to the fifth. The energy position for the first peak of the N 2 1s vibrational structure is at 400.77 eV (Sodhi & Brion, 1984). The reference energies, their energetic positions and accuracy for all available structures are summarized in Fig.…”

High-quality metrology with synchrotron radiation requires in particular a very high spectral purity of the incident beam. This is usually achieved by a set of transmission filters with suitable absorption edges to suppress high-order radiation of the monochromator. The at-wavelength metrology station at a BESSY-II bending-magnet collimated plane-grating monochromator (c-PGM) beamline has recently commissioned a high-order suppression system (HiOS) based on four reflections from mirrors which can be inserted into the beam path. Two pairs of mirrors are aligned parallel so as not to disturb the original beam path and are rotated clockwise and counter-clockwise. Three sets of coatings are available for the different energy ranges and the incidence angle is freely tunable to find the optimum figure of merit for maximum suppression at maximum transmission for each photon energy required. Measured performance results of the HiOS for the EUV and XUV range are compared with simulations, and applications are discussed.
