Editing X-ray absorption fine structure (section)

=== Extended X-ray absorption fine structure ===

The oscillatory structure extending for hundreds of [[electron volt]]s past the edges was called the “Kronig structure” after the scientist, [[Ralph Kronig]], who assigned this structure in the high energy range ( i.e., for a kinetic energy range - larger than 100 eV - of the photoelectron in the weak scattering regime) to the single [[scattering]] of the excited [[photoelectron]] by neighbouring atoms in molecules and condensed matter.<ref name="exafs1">{{cite journal | last1=Rehr | first1=J.
