AbstractAbstract
[en] The ratio of the proton's elastic electromagnetic form factors, GEp/GMp, was obtained by measuring Pt and Pell, the transverse and longitudinal recoil proton polarization components, respectively, for the elastic (rvec e)p → e(rvec p) reaction in the four-momentum transfer squared range of 0.5 to 3.5 GeV2. In the single photon exchange approximation, the ratio GEp/GMp is directly proportional to the ratio Pt/Pell. The simultaneous measurement of Pt and P#ell# in a polarimeter reduces systematic uncertainties. The results for the ratio GEp/GMp show a systematic decrease with increasing Q2, indicating for the first time a definite difference in the distribution of charge and magnetization in the proton. The data have been reanalyzed and systematic uncertainties have become significantly smaller than previously published results
