Quasielastic Electron-Deuteron Scattering and Neutron Electromagnetic Form Factors at Q(2) = 1.75 to 4.00 (GEV/C)(2)

Cross sections for electron-deuteron scattering measured using the Nuclear Physics Injector beam at The Stanford Linear Accelerator Center are reported. Data was obtained with the SLAC 8 GeV spectrometer at electron scattering angles between 15^circ and 90^circ and momenta between 0.5 and 7.5 GeV. Data was taken simultaneously in the SLAC 1.6 GeV spectrometer which was fixed at 90 ^circ and detected scattered electrons with momenta between 0.5 and 0.8 GeV. Experimental cross sections are presented for Q^2=1.75 to 4.00 (GeV/c)^2 as well as the separated longitudinal and transverse components, R_{L} and R_ {T}. Neutron electromagnetic form factors were extracted from the separated R_{L } and R_{T}^ectra using a PWIA model of the quasielastic peak. Sensitivity to deuteron wave function models and relativistic corrections are examined. The extracted neutron form factors are compared with various predictions and fits to previous data. Cross sections for electron-aluminum scattering in the 8 GeV spectrometer are reported with the extracted structure function, nu W_2, and the ratio of longitudinal to transverse cross sections, R.
