Polarization transfer in the {sup 4}He({rvec e}, e'{rvec p}){sup 3}H reaction at a Q{sup 2} of 0.4 (GeV/c){sup 2} was measured at the Mainz Microtron MAMI. The ratio of the transverse to the longitudinal polarization components of the ejected protons was compared with the same ratio for elastic ep scattering. The results are consistent with a recent fully relativistic calculation which includes a predicted medium modification of the proton form factor based on a quark-meson coupling model.
