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 polarization of the recoil proton, PL and PT, respectively, in the elastic scattering of polarized electrons, \(\vec{e}p\rightarrow e\vec{p}\). Together these experiments cover the Q2 range 0.5 to 5.6 GeV2. A new experiment is currently being prepared, to extend the Q2 range to 9 GeV2 in Hall C.
