摘要：

We have measured inelastic electron-deuteron, electron-proton, and electron-aluminum cross sections at 10-degrees 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 Q2=2.5, 4.0, 6.0, 8.0, and 10.0 (GeV/c)2. The ratio of elastic cross sections sigma(n) /sigma(p) falls with increasing Q2 above 6 (GeV/c)2. The inelastic data are compatible either with y scaling (scattering from a single nucleon) or with xi-scaling (scattering from quarks).
