Effect of the LIII Absorption Edge of Uranium on Chemical Shifts of the Lβ1 Line of Uranium in UO2+x

The effect of intraatomic absorption of the Lβ1 X-ray emission line of uranium was studied. To eliminate the effect of the LIII absorption edge on the chemical shift (δ) of the Lβ1 line, the dependence of δLβ1 on the oxygen index x in oxide systems of variable composition UO2+x was determined indirectly. It was shown that, in the absence of the effect of the LIII absorption edge, the dependence of δLβ1 on x is ordinary and, as in the case of other hard emission lines of the uranium L series, can be described by a second-order polynomial. The abnormal dependence of δLβ1 on x is explained.

State and distribution of atoms in GeXrinX (X = S, SE) from K-spectral emission data

The authors study the chemical shifts and x-ray emission lines of Ge, Se, and In in order to quantify the mutual effect of atoms present in the lattice of a glass, particularly their effective charges. They describe their experimental setup and set forth in a number of charts and tables their experimental results, which they analyze at length, with particular attention to the compatability between the chemical shifts and effective charges of atoms bound chemically with each other.
