TL;DR: The oxygen K x-ray-absorption near-edge structure of alkaline-earth-metal and 3d-transition-metal oxides has been measured by means of the photoelectric yield method and the short-range order multiple scattering calculations for O K-edge spectra of CaO and TiO have been performed.

TL;DR: In this paper, the authors measured the x-ray $K$ absorption spectra of Nb and Mo in layer transition-metal disulfides using a Yohan-type curved-crystal spectrometer, and obtained information on detailed band structures of both occupied and empty states, which were not inconsistent with other experimental results, such as the reflectivity and the energy-loss spectra.

TL;DR: The soft-x-ray absorption spectra due to excitation of $3p$ electrons of transition metals, Cr, Mn, Fe, Co, and Ni, and the metal ions in the halides, Cr${\mathrm{Cl}}_{2}$, Cr${Br}}_{3}, Mn${F}}{2}], Mn{{Cl}, Mn{M}{Br}, Mn{Cl}, and Ni${Ni}, Ni} are obtained at room temperature as discussed by the authors.

TL;DR: In this article, a monochromatic light spot of 0.5 mm in diamter was obtained at the fixed sample position with the aid of a toroidal postfocussing mirror.

TL;DR: In this paper, the F-K X-ray absorption near edge structure (XANES) spectra of alkaline-earth fluorides have been measured with a high energy resolution using synchrotron radiation.
