EXAFS cumulants of Nickel crystal

High-order anharmonic effective potentials and four EXAFS cumulants have been studied taking into account the influence of the nearest neighbors of absorbing and backscattering atoms by Analytical expressions of th quantum potential expanded in the fourth order which influences from the 4thcumulants. Numerical results for Ni are found to be in good a experiment and the classical theory.
