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$\sp\circ$ and 90$\sp\circ$ 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$\sp\circ$ and detected scattered electrons with momenta between 0.5 and 0.8 GeV. Experimental cross sections are presented for $Q\sp2=1.75$ to 4.00 (GeV/c)$\sp2$ as well as the separated longitudinal and transverse components, $R\sb{L}$ and $R\sb{T}.$ Neutron electromagnetic form factors were extracted from the separated $R\sb{L}$ and $R\sb{T}$ spectra 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, $
u W\sb2,$ and the ratio of longitudinal to transverse cross sections, R.
