PURPOSE: To obtain a K absorption edge measuring device which can apply the stably high electric power source voltage with high precision from a high voltage power source to a radioactive ray generator and correctly carries out the qualitative and quantitative analyses for a substance.TAJIMA TSUTOMU...
The fine structure in the titanium x-ray K -edge absorption has been measured in Ti 1 x Nb x O 2 mixed dioxides ( x =0鈥 0.1) with rutile structure in a laboratory-type spectrometer by total electron quantum-yield measurement. The position of the XANES lines is shown to be in good...
The lithium K absorption edge has been studied as a function of momentum transfer in a high-resolution inelastic-electron-scattering experiment and found to exhibit no significant change with momentum transfer up to 1.2 Å-1. This result places severe restrictions on theories which interpret the ...
It has been found that a striking correlation exists between the plasman energy in solids and the chemical shifts of the X-ray K-absorption edges of the transition elements Cr, Cu, Ni, Co, Zn and their compounds. Fairly good agreement between the calculated values of the plasmon energies ...
The shift of the K-absorption edge (ΔEk) was measured in ternary alloys of Ga30Se70-xInx (x = 0, 5, 10, 15, 20) with respect to the binary Ga30Se70 alloy. It was observed that the K-edge of selenium shifted progressively towards the lower energy side as the indium concentratio...
The effect of monochromatic X-ray irradiation on iodine occurred with the X-ray of 33.2 keV which corresponds to the energy just above the K-absorption edge energy of this element. Results of experiments using three different energy levels (33.0, 33.2 and 33.4 keV) demonstrated that spheroid de...
Systematic measurements of Co K-edge spectra have been carried out for a series of cobalt(III) complexes. A counterion effect has been observed in the higher energy region of the XANES. The energy of the 1s-3d transition increased in the following order: dtc - < ox 2- < NO 2- < phen...
absorption energy, this approach allows using the theoretical approximation of 3.9 electrons29for sufficiently accurate anomalous occupancy refinements. In summary, we collected a complete SAD dataset at a wavelength of 3.35 Å, which is close to the K absorption edge (3.44 Å), resulting ...
The X-ray K absorption edges of Ge and Se in glassy Ge22Se78−x Bi x with x =0, 2 and 10 have been studied in bulk as well as in thin-film form. In both cases, we find that, at a low concentration of Bi (x =2), the Se K edge shifts while that of Ge remains unchang...
