Phase shift analysis and extraction of structure functions for Coulomb distortion on (e, e ' p) reactions at high electron energies

In this paper we improve, our approximate phase shifts of the electron wave functions by including Coulomb distortion effects from medium and heavy nu clei oil exclusive (e, c(i)p) reactions in the quasielastic region. The now phase shifts arc, parameterized for the elastic electron scattering and wo rk very well at incident electron energies greater than 300 MeV. The struct ure functions with the new phase shifts for the electron wave functions are extracted, We use a relativistic single-particle model as applied to Pb-20 8 and to recently measured data at CEBAF on O-16 (e,e'p) to investigate the electron Coulomb distortion effects and to extract the structure functions with the now phase shifts.
