An analysis of the extended x-ray absorption fine structure (EXAFS) on the $L_{2,3}$ edges of Au shows significant contributions from both the $d$- and $s$-symmetric final states. The contribution to the EXAFS of the final $s$ states relative to the final $d$ states decreases as the energy increases past the edge. Local structure can be determined by Fourier transforming $L$-edge EXAFS data, similar to the case of the $K$ edge.
