摘要：

Quasielastic e-d cross sections have been measured at forward and backward angles. Rosenbluth separations were done to obtain R(L) and R(T) at Q2 = 1.75, 2.50, 3.25, and 4.00 (GeV/c)2. The neutron form factors G(En) and G(Mn) 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 G(Mn) are consistent with the dipole form, while G(En) 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.
