The longitudinal and transverse components of the polarization of the outgoing proton were measured for the reaction ¹⁶O(e,e˘ p) at a four-momentum transfer squared of 0.8 GeV² in quasifree kinematics. These were the first measurements of polarization transfer observables for a complex nucleus. Comparison of the ratio of the transverse and longitudinal polarization to theoretical predictions allows the study of modification of the proton's form factors in the nuclear medium.
