• Possible ambiguities in the theoretical interpretation of exclusive (e, e'p) reactions are discussed on the basis of realistic model calculations. Gauge ambiguity, medium effects, and contribution of the Δ current are evaluated in distorted wave Born approximation (DWBA) where the four momentum transfer square |q_μ|^2 is less than 0.5(GeV/c)^2. The gauge ambiguity effects are shown to be about 10% in the small missing momentum region and about 20% maximally in the high missing momentum region. Medium effects of about 6-10% appear mainly in the small missing momentum region. The Δ-resonance current influences the high missing momentum region by about 10% maximally.
