(a) Experimental U L3-edge XANES spectra and their pseudo-Voigt line shapes by least-squares fitting in linear combination analyses for (NH4)4UO2(CO3)3 powder. (b) Experimental U L3-edge XANES spectra and their pseudo-Voigt line shapes by least-squares fitting in linear combination analyses for UO22+–AO complex. The inset shows the corresponding k-weighted EXAFS χ(k) function. |
