Quasielastic Scattering from Relativistic Bound Nucleons: Transverse-Longitudinal Response

Predictions for electron induced proton knockout from $p_{1/2}$ and $p_{3/2}$ shells in ${}^{16}\mathrm{O}$ are presented using various approximations for the relativistic nucleonic current. Results for differential cross section, transverse-longitudinal response ( $R_{\mathrm{TL}}$), and left-right asymmetry $A_{\mathrm{TL}}$ are compared at $|Q^2|=0.8\mathrm{}(\mathrm{GeV}/c{)}^2$. We show that there are important dynamical and kinematical relativistic effects which can be tested by experiment.
