[en] We present the results of an accurate investigation of the electromagnetic and weak radiative corrections to Bhabba scattering at PETRA/PEP energies and around the Z⁰ in the electroweak standard model. Using the on shell renormalization scheme with the electric charge and the boson and fermion masses as renormalized parameters we find that the photonic corrections to the γ and Z⁰ exchange contributions are the most important ones at PETRA energies, on resonance, ans in the radiative tail region above the Z⁰. The fominating weak correction is the Z⁰ self energy which gives visible effects around the resonance. (orig.)
