Abstract
We use the relativistic distorted-wave impulse approximation (RDWIA) to study the effects of negative-energy components of Dirac wave functions on the left-right asymmetry for reactions on with and with . Spinor distortion is more important for the bound state than for the ejectile and the net effect decreases with . Spinor distortion breaks Gordon equivalence and the data favor the CC2 operator with intermediate coupling to the sea. The left-right asymmetry for is described well by RDWIA calculations, but at the observed variation with missing momentum is flatter than predicted.
