Measurement of Proton Electromagnetic Form Factors via the Spin Transfer Reaction
Abstract
A measurement of GE(P)/GM(P) at squared Q values of 0.38 and 0.50 GeV(2) was performed at Bates Linear Accelerator Center using a focal plane polarimeter (FPP) to measure the recoil proton polarization following elastic scattering of polarized electrons on a hydrogen target. These are the first measurements of all three polarization components and determination of the proton's form factors via spin transfer rather than Rosenbluth separation. The ratio GE(P)/GM(P) is obtained in a nearly systematic free manner. The measured polarizations are consistent with the Plane Wave Impulse Approximation (PWIA). This is the first experiment to use the newly built BATES-FPP and that device is described in detail.
