Exclusive Electron Scattering from Deuterium at High Momentum Transfer

Cross sections are presented for the reaction ${}_{}{}^2{}_{}{}^{}H\left({e,e}^{\prime }p\right)n$ for momentum transfers in the range $1.2\le Q^2\le 6.8(\mathrm{GeV}/c{)}^2$ and for missing momenta from 0 to 250 MeV/c. The longitudinal-transverse interference structure function has been separated at $Q^2=1.2\mathrm{}(\mathrm{GeV}/c{)}^2$. The observables are compared to calculations performed in nonrelativistic and relativistic frameworks. The data are best described by a fully relativistic calculation.
