Radiative corrections to the electron scattering from nucleons and nuclei at high energies (> 50 MeV) are considered. Many formulas in the MO and Tsai’s article in-Review of Modern Physics are improved--rc-- *. and better derivations of them are presented. The effects of the strag-gling of electrons in the medium due to both the external bremsstrahlung and the i.onization are included in the radiative corrections. A method for dealing with the radiative corrections to the scattering from a target material with a large Z is proposed, We suggest that the proper way to deal with the radiative corrections to the coincidence experiments is in terms of the energy-momentum distribution and the density matrix of the virtual photon exchanged; formulas needed for dealing with the problem this way are presented.
