Abstract
The total cross section for Compton scattering off atomic electrons, γ + e→γ′+e′, was measured using photons with energies between 6.5 and 11.1 GeV incident on a ⁹Be target as part of the PrimEx-eta experiment in Hall D at Jefferson Lab. This is the first measurement of this fundamental QED process within this energy range. The total uncertainties of the cross section, combining the statistical and systematic components in quadrature, averaged to 3.4 % across all energy bins. This not only demonstrates the capability of this experimental setup to perform precision cross-section measurements at forward angles but also allows us to compare with state-of-the-art QED calculations.
