  The first (e,e'p) polarization transfer measurements on a nucleus heavier
than deuterium have been carried out at Jefferson Laboratory. Transverse and
longitudinal components of the polarization of protons ejected in the reaction
16O(e,e'p) were measured in quasielastic perpendicular kinematics at a Q^2 of
0.8 (GeV/c)^2. The data are in good agreement with state of the art
calculations, but do not exclude possible changes in the ratio of the electric
to magnetic form factors of the nucleon in the nuclear medium at the level of
recent theoretical predictions.
