We have measured the cross section for quasielastic 1p -shell proton knockout in the {sup 16}O( e, e{sup '}p) reaction at {omega}=0.439 GeV and Q{sup 2}=0.8 (GeV/c){sup 2} for missing momentum P{sub miss}{<=}355 MeV /c . We have extracted the response functions R{sub L+TT} , R{sub T} , R{sub LT} , and the left-right asymmetry, A{sub LT} , for the 1p{sub 1/2} and the 1p{sub 3/2} states. The data are well described by relativistic distorted wave impulse approximation calculations. At large P{sub miss} , the structure observed in A{sub LT} indicates the existence of dynamical relativistic effects. (c) 2000 The American Physical Society.
