Optical potentials obtained from elastic proton scattering have been successfully used to describe the final state interaction in ([ital e],[ital e][prime][ital p]) reactions. However, spectroscopic factors extracted from experimental data are often quite different depending on whether relativistic calculations or nonrelativistic calculations are used. Since the calculation of the ([ital e],[ital e][prime][ital p]) cross section requires the wave functions of the outgoing proton in the nuclear interior, different optical potential models could cause the differences in these calculations. We use a model which can take either nonrelativistic or relativistic optical potentials while keeping all other aspects of the calculation the same, and find that a relativistic optical potential compared with a nonrelativistic optical potential can cause a difference as much as 14%. We examined several optical models as well as the use of the Perey factor in nonrelativistic calculations.
