The Use of EXAFS in the Study of Polymeric Electrolytes
In conventional X-ray absorption experiments the absorption coefficient for any particular element varies smoothly with the energy/wavelength of the incident photon beam. When the beam energy is sufficiently high enough to overcome the binding energy of a core electron, a photoelectron will be ejected. The abrupt change in absorption of the incident beam is referred to as an absorption edge, and these features are superimposed on the smooth curve; thus, a K edge refers to the minimum energy required to eject a is electron and the closely spaced L edges refer to ejection of 2s and 2p electrons.
