Abstract

Recoil polarimetry was used to extract the ratio of the proton electromagnetic form factors, μ_p G_E^p/ G_M^p = 0.878 ± 0.064(stat) ± 0.012(sys), at Q² = 1.13 (GeV/c)² from the reaction ¹H(e, ep). This was an ancillary measurement in which the proton polarization was determined as part of a larger program utilizing a stand-alone polarimeter designed to measure μ_n G_Eⁿ/G_Mⁿ. This measurement complements previous recoil polarimetry measurements of μ_p G_E^p/G_M^p made at the Thomas Jefferson National Accelerator Facility.
