    "abstract": "We use the relativistic distorted-wave impulse approximation (RDWIA) to study\nthe effects of negative-energy components of Dirac wave functions on the\nleft-right asymmetry for (e,e\u0027p) reactions on 16-O with 0.2 \u003c Q^2 \u003c 0.8 and\n12-C with 0.6 \u003c Q^2 \u003c 1.8 (GeV/c)^2. Spinor distortion is more important for\nthe bound state than for the ejectile and the net effect decreases with Q^2.\nSpinor distortion breaks Godon equivalence and the data favor the CC2 operator\nwith intermediate coupling to the sea. The left-right asymmetry for Q^2 \u003c 1.2\n(GeV/c)^2 is described well by RDWIA calcuations, but at Q^2 = 1.8 (GeV/c)^2\nthe observed variation with missing momentum is flatter than predicted.",
