The low energy features of XANES (X-ray absorption near edge structure) in the X-ray K -absorption edge of transition metal systems have long been detected and attempts have been made to explain their origin. Only recently have some theoretical approaches based upon multiple scattering (MS) ...

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 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 ...
Oxygen K-absorption spectra were measured for La-, Y-, and Nd-system high-Tc superconductors. The spectrum of insulator for La- and Y-systems has a small structure about 1 eV above the absorption edge, being assigned to the Cu3d10 state. Hole-doping prod
The edge shift is found to be dependent on the difference in electronegativity between the metallic atoms and the Ge or Se atoms. The results are in agreement with Pauling''s concept of electronegativity and indicate that the nature of the bonds in these glasses is iono-covalent in character ...

The fine structure in the titanium x-ray K-edge absorption has been measured in Ti1−x NbxO2 mixed dioxides (x=0–0.1) 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 agreement ...
