An EXAFS study has been performed on annealed and cold-rolled copper foils in order to understand the structural change after deformation. Data taken from a cold-rolled specimen showed nearly identical nearest neighbor structure as compared to an annealed specimen. However, larger Debye-Waller factors and static displacements were observed for atoms in the higher coordination shells. Furthermore, increased disorder in the deformed specimen resulted in a reduced EXAFS amplitude. The determination of the electron mean free path and the effect of specimen non-uniformity on the transmission EXAFS amplitude are also discussed.
