The reliability of the models describing the final-state interactions in ({ital e},{ital e}{sup {prime}}{ital p}) scattering at high proton energies is an important issue in view of the experiments planned at CEBAF. One of the most popular approaches adopted, the Glauber method, involves the linearization of the wave equation for the ejected proton traveling through the residual nucleus. We have studied the consequences of such an assumption for the case of the {sup 12}C({ital e},{ital e}{sup {prime}}{ital p}){sup 11}B{sup {asterisk}} reaction at high proton momenta by comparing the results with the predictions obtained when the second-order differential equation for the proton wave is solved exactly for each partial wave. We find that the two methods give well-correlated angular distributions for momenta in the range 1{endash}4 GeV/{ital c}, i.e., for kinematics relevant to the transition to the eikonal regime. {copyright} {ital 1996 The American Physical Society.}
