Anomalous Scattering Factors near the Zn K Absorption Edge Estimated from the Absorption Coefficient Measurement of ZnFe2O4

The X-ray linear absorption coefficient for ZnFe2O4 was measured near the Zn K absorption edge in the energy region between 9 and 11 keV. The result was used for determining the imaginary part of the anomalous dispersion factors f” (E) as a function of energy E. The real part of the anomalous scattering factor f' (E) was also estimated from the f” (E) data through the dispersion (Kramers-Krönig) relation. The experimental f'(E) values agree almost within the error bars with the data calculated by the Cromer-Liberman scheme, except for the energy region about 400 eV above the absorption edge.
