We propose an effective current operator for nucleon electromagnetic knockoutthat incorporates spinor distortion and density-dependent nucleon form factorsusing an effective momentum approximation. This method can be used in acoordinate-space approach with either relativistic or nonrelativistic opticalpotentials and overlap functions. We studied these effects for the$^{16}O(\vec{e},e' \vec{p})$ reaction at Q^2 = 0.8 (GeV/c)^2. Spinor distortionsubstantially enhances the left-right asymmetry while reducing the ratiobetween sideways and longitudinal recoil polarization for p-shell knockout byabout 5% for modest missing momenta. We also find that the density dependenceof nucleon form factors suggested by a quark-meson coupling model reduces thepolarization ratio further. Much larger effects are obtained for the s-shellthan for p-shell. However, both effects are subject to much larger Gordonambiguities than comparable nonrelativistic calculations.Comment: 20 pages, including 8 figures. Intended for Phys. Rev.
