Shell indicates the type of ligands for each shell of the fit, *N* is the coordination number, *R* is the metal-scatterer distance, *σ*^{2} is a mean square deviation in *R* and ∆*E*_{0} is the shift in *E*_{0} for the theoretical scattering functions. Numbers in parentheses were not varied
during optimization

The errors of data and fits are roughly estimated from the change of the residual
factors to be 5% for *N*, 0.25% for *R*, 10% for *σ*^{2} and 4 eV for ∆*E*_{0}. No ambiguities of the theoretical standards are included
