We measured the cross section and response functions for the quasielastic {sup 16}O( e,e'p) reaction for missing energies 25{<=}E{sub m}{<=}120 MeV at missing momenta P{sub m}{<=}340 MeV/c . For 25<E{sub m}<50 MeV and P{sub m}{approx}60 MeV/c , the reaction is dominated by a single 1s{sub 1/2} proton knockout. At larger P{sub m} , the single-particle aspects are increasingly masked by more complicated processes. Calculations which include pion exchange currents, isobar currents, and short-range correlations account for the shape and the transversity, but for only half of the magnitude of the measured cross section.
