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, P_L and P_T, 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.
