The JLab E93-038 collaboration measured the electric form factor of the neutron, G^n_E, via quasi-elastic scattering from the d( e,e' n)p reaction at three values of the squared four-momentum transfer Q^2 [viz., 0.45, 1.15, and 1.47 (GeV/c)^2]. By measuring the ratio of two scattering asymmetries associated with two different precession angles of the neutron polarization vector, systematic uncertainties are small because the neutron polarimeter analyzing power and the electron beam polarization cancel in the ratio. Preliminary results of a first-pass analysis of the data indicate that G^nE follows the parameterization of Galster et al.(S. Galster, H. Klein, J. Moritz, K.H. Schmidt, D. Wegener, and J. Blechwenn, Nucl. Phys. B\underline32), 221 (1971). Measured results will be discussed and compared with world data.
