High precision measurement of Compton scattering in the 5 GeV region

The PrimEx Collaboration

Research output: Contribution to journalArticle


The cross section of atomic electron Compton scattering γ+e→γ+e was measured in the 4.400–5.475 GeV photon beam energy region by the PrimEx collaboration at Jefferson Lab with an accuracy of 2.6% and less. The results are consistent with theoretical predictions that include next-to-leading order radiative corrections. The measurements provide the first high precision test of this elementary QED process at beam energies greater than 0.1 GeV.
