We have measured inelastic electron-deuteron, electron-proton, and electron-aluminum cross sections at 10\ifmmode^\circ\else\textdegree\fi{} in the kinematic region between elastic deuteron scattering and the second resonance region at six beam energies between 9.8 and 21 GeV. The elastic electron-neutron cross section was extracted from the quasielastic data at ${Q}^{2}=2.5,4.0,6.0,8.0, \mathrm{and} 10.0$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$. The ratio of elastic cross sections $\frac{{\ensuremath{\sigma}}_{n}}{{\ensuremath{\sigma}}_{p}}$ falls with increasing ${Q}^{2}$ above 6 ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$. The inelastic data are compatible either with $y$ scaling (scattering from a single nucleon) or with $\ensuremath{\xi}$ scaling (scattering from quarks). |
