Polarization transfer in quasi-elastic nucleon knockout is sensitive to theproperties of the nucleon in the nuclear medium. In experiment E03-104 atJefferson Lab we measured the proton recoil polarization in the 4He(e,e'p)3Hreaction at a Q^2 of 0.8 (GeV/c)^2 and 1.3 (GeV/c)^2 with unprecedentedprecision. The measured polarization-transfer coefficients transverse andlongitudinal to the momentum-transfer direction are well described by a fullyrelativistic calculation when a density-dependent medium modification of thenucleon form factors is included in the model. Results of an alternative modelshow that the ratio of these observables is also well described through strongcharge-exchange final-state interactions. The induced polarization in the(e,e'p) reaction is sensitive to the final-state interactions and the data fromE03-104 will further constrain these models.
