Coulomb corrections for quasielastic scattering of electrons by nuclei are calculated using eikonal distorted waves. Corrections to the lowest-order eikonal approximation are included to obtain accurate results. Spin-dependent eikonal phase shifts are evaluated and they yield very small corrections to the longitudinal and transverse cross sections at electron energies of 500 MeV or higher. Because of this the Rosenbluth procedure is accurate for separation of the longitudinal and transverse response functions. The effective-momentum approximation is also found to be accurate with regard to removal of the remaining Coulomb effects from the distorted waves. Calculations are presented for electron scattering from 208Pb and 56Fe nuclei at energies of 500 and 800 MeV and momentum transfers q=550 and 900 MeV/c.
