However, higher order measurements are required to test QED.  Delbrück scattering is a higher order process, which involves the scattering of photons off the Coulomb fields of nuclei and is the only one which has been measured due to its large cross section.  We have found recently that polarized gamma ray sources can achieve high precision measurements of Delbrück scattering.  Currently, there are many petawatt-class laser facilities operating, being constructed, and planned around the world.  Such laser systems can produce extremely high flux highly polarized gamma rays in laser-plasma, electron beam-laser interactions. Therefore, they have the possibility of measuring Delbrück scattering to high precision. We believe this will be of great interest to the plasma and fusion research community at large.
