Title Measurements of the Electric Form Factor of the Neutron at Q2 = 1.7 and 3.5 GeV^2
Abstract A measurement of the electric form factor of the neutron, Gn E, was performed at Q2 = 1.3, 1.7, 2.4, and 3.5 GeV2 at Thomas Jefferson National Accelerator facility. This was done using a double polarization technique by measuring the helicity dependent quasi-elastic cross section asymmetry from the semi-inclusive reaction 3He(e,e'n)pp. This asymmetry can then be directly related to the ratio of the electric and magnetic form factors of the neutron. In this analysis we present results for two of the measurements performed in this experiment, Q2 = 1.7 and 3.5 GeV2, which represent the first points analyzed for this experiment. The 3.5 GeV2 point is of particular interest due to the lack of previous precision data above 2.0 GeV2. We find the value for our lower momentum transfer point, Q2 = 1.7 GeV2, GnE = 0.0342±stat 0.0023±sys 0.0040, consistent with existing world data and our highest point, Q2 = 3.5 GeV2, Gn E = 0.0117±stat 0.0030±sys 0.0010, consistent with the Galster parametri
