The Electric Form Factor of the Neutron at Q2 = 1.17 and 1.47(GeV/c)2 from the 2H (e, en)' H reaction

The Jefferson Laboratory E93-038 collaboration measured the ratio of the electric form factor to the magnetic form factor of the neutron, g (triplebond) GEn/GMn, via recoil polarimetry from the quasielastic 2H((rvec e), e(prime)(rvec n))1 H reaction at Q2 = 0.45, 1.17 and 1.47 (GeV/c)2 in Hall C of the Thomas Jefferson National Accelerator Facility. A polarimeter designed specifically for E93-038 was used to measure the up-down scattering asymmetry from the transverse component of the recoil neutron's polarization vector, and a dipole magnet located in front of the polarimeter was used to precess the polarization vector in the scattering plane through an angle of χ. Sequential measurements of the scattering asymmetry with the polarization vector precessed through angles χ = 0o and χ = ±90o for Q2 = 1.47 (GeV/c)2 were made during January 2001 and through angles χ = ±40o for Q2 = 1.17 (GeV/c)2 during April 2001 and will be reported on in this dissertation. This ratio method removes the need to know the analyzing power.
