Abstract:
The ratio of the electric and magnetic proton form factors,G Ep G Mp , has been obtained in two Hall A experiments, from measurements of the longitudinal and transverse polarizations of the recoil proton,P l andP t , in the elastic scattering of polarized electrons, 
$$overrightarrow e p to eoverrightarrow p $$
. Together these experiments cover theQ 2 range of 0.5 to 5.6 GeV2. A new experiment is currently being prepared, to extend theQ 2 range to 9 GeV2 in Hall C.
Keywords:Proton  electromagnetic  structure
