We have measured the cross section for quasielastic 1p-shell proton knockout in the 16O(e,ep) reaction at ω  =  0.439 GeV and Q2  =  0.8 (GeV/c)2 for missing momentum Pmiss≤355 MeV/c. We have extracted the response functions RL+TT, RT, RLT, and the left-right asymmetry, ALT, for the 1p1/2 and the 1p3/2 states. The data are well described by relativistic distorted wave impulse approximation calculations. At large Pmiss, the structure observed in ALT indicates the existence of dynamical relativistic effects.
