Abstract: A comparison between nonrelativistic and relativistic descriptions of the ${(e,e}^{\ensuremath{'}}p)$ reaction is presented. We use the nonrelativistic DWEEPY code and develop a fully relativistic model starting from the effective Pauli reduction for the scattering state and the relativistic mean field theory for the bound state. Results for the ${}^{16}\mathrm{O}{(e,e}^{\ensuremath{'}}p)$ differential cross section and structure functions are compared in various kinematic conditions. A limit in energy of the validity of the nonrelativistic approach is established. The effects of spinor distortion and of the effective momentum approximation for the scattering state are discussed. A satisfactory agreement with data of differential cross sections, structure functions, and polarization observables is achieved.
