Tables

Generic image for table
Table I.

Parameters of local structure around Y atoms. N is the coordination number. R is the bond length. is the Debye-Waller-like factor. is the difference between the zero kinetic energy value of the sample and that of the theoretical model used in FEFF. Underlined values were kept constant during fitting. Uncertainties were estimated by the double-minimum residue method.
