Coulomb effects in quasielastic electron scattering

Coulomb distortion plays an important role in interpreting both (e,e') and (e,e,'p) reactions in the quasielastic region. A fully distorted partial wave calculation is presented, and the results are compared with the widely-used plane wave approximation and other distorted-wave calculations. The new calculation seems to give higher occupation numbers in the (e,e'p) reactions. The usefulness of the (e,e'p) reaction in studying different nuclear optical potentials is discussed. Also considered are the effects of electron Coulomb distortion in the separation of longitudinal and transverse structure functions in (e.e')
