Abstract
A new technique is proposed for calculating the extended X-ray absorption fine structure (EXAFS). The only assumption needed is that the actual potential can be replaced by a sum of non-overlapping muffin-tin potentials. Then the integral equation of the scattering theory is shown to give a direct and revealing account of the oscillatory effects in the photo absorption spectrum.File in questo prodotto:
