| Analysing the EXAFS of several Mn and Co systems, the absorbing atom phase shift α and backscattering amplitude phase shift β are evaluated. It is shown that the parameters α and β vary linearly with the nearest neighbour distance, R, except in the systems CoCl2 · 6H2O, MnSO4 · H2O and MnF2. The nearest neighbour distance, R, in the complicated systems like smaltite and braunite minerals was also determined. The values are close to the crystallographic values. |
