Kinematical versus dynamical relativistic effects in A(vec{e},e'vec{p})B

The relativistic mean field approach is applied to the description of coincidence $A(e,e'p)B$ reactions where both the incident electron beam and knockout proton are polarized. Effects introduced by the dynamical enhancement of the lower components of the bound nucleon wave function are analyzed within RPWIA for the polarized responses and transferred polarizations. Results obtained by projecting out the negative-energy components are also compared with various nonrelativistic reductions.
