• Quasielastic [ital e]-[ital d] cross sections have been measured at forward and backward angles. Rosenbluth separations were done to obtain [ital R][sub [ital L]] and [ital R][sub [ital T]] at [ital Q][sup 2]=1.75, 2.50, 3.25, and 4.00 (GeV/[ital c])[sup 2]. The neutron form factors [ital G][sub [ital E][ital n]] and [ital G][sub [ital M][ital n]] have been extracted using a nonrelativistic model. The sensitivity to deuteron wave function, relativistic corrections, and models of the inelastic background are reported. The results for [ital G][sub [ital M][ital n]] are consistent with the dipole form, while [ital G][sub [ital E][ital n]] is consistent with zero. Comparisons are made to theoretical models based on vector meson dominance, perturbative QCD, and QCD sum rules, as well as constituent quarks.
