Abstract
Full text: First order EXAFS analysis calculates the interaction of the outgoing photo-electron with nearby atomic neighbours. Until now a second order solution has relied upon calculations of multiple scattering of this photo-electron. We propose an entirely new solution as the second order term in the EXAFS spectrum which investigates the role of the decay channels of the excited atom in modifying the local attenuation coefficient or EXAFS structure. We present absolute EXAFS data for the K-edge of copper and the L1-edge of gold. Using a simultaneous measurement of x-ray fluorescence and transmission EXAFS data, we explore a correlation between the EXAFS oscillations and the intermediate decay channels of the target atom as measured in fluorescence detector. We will discuss the multi-configuration Dirac Fock (MCDF) calculation and its implications. The results will also be considered in relation to the possibility of atomic EXAFS.
