Abstract:

The regularization method of solving ill-posed problem is used to determine five partial interatomic distances on the basis of combined two EXAFS spectra. Mathematical algorithm and experimental results of the EXAFS analysis for NicZn1-cO (c=0.0, 0.3, 0.5, 0.7,1.0) solid solutions with the rock salt (rs) crystal structure are discussed. Samples were synthesized from the binary oxide powders at pressure of 7.7 GPa and temperatures 1450-1650 K. The measurements were performed using synchrotron facilities (Russian Research Centre ``Kurchatov Institute{''
