    • By inserting only the cell side as a ``global'' geometrical parameter we implicitly assume that mean distances and angles coincide with that of the model bcc structure. This is not necessarily true, because EXAFS probes correlated distances and angles and therefore slight deviations of these quantities could be observed, depending on the local vibrational modes. However, the present assumption greatly reduces the independent fitting parameters and has been preferred although leading to a slight worse agreement between calculated and experimental data.
