  Outgoing nucleon polarization in exclusive deuteron electrodisintegration is
studied at the quasi-elastic peak in the standard theory with emphasis on the
effect of nucleonic and pionic relativistic corrections. The cases of polarized
beam or/and polarized target are considered. Sizeable relativistic effects are
pointed out in several polarization components. The sensitivity of nucleon
polarization to the neutron charge form factor $G_E^n$ is discussed. In
particular, it is shown that the longitudinal component of neutron polarization
with vector polarized deuterons is as sensitive to $G_E^n$ as the sideways beam
polarization transfer.
