Abstract

Measurements of the cross section for the reaction

e^{+} e^{-} \to e^{+} e^{-}

(Bhabha scattering) at angles close to 90°, relative to Bhabha scattering at 4°, are reported at center-of-mass energies of 7.0 and 7.4 GeV. The results are in agreement with quantum electrodynamics, and new limits on cutoff parameters for the photon propagator are given.
