摘要：

Cross sections for inclusive electron scattering from aluminum have been measured at both forward and backward angles in the kinematic region near x = 1 and 1.75 < Q2 < 7 (GeV/c)2. The forward-angle data are in good agreement with a recent calculation. Both the data and the calculation show scaling behavior for F2(xi,Q2) = nuW2(xi,Q2) at high Q2 for fixed values of the Nachtmann variable xi. The ratio R = sigma(L)/sigma(T) has been extracted for 1.75 < Q2 < 5 (GeV/c)2 and is found to decrease with Q2 to a value consistent with zero at the highest Q2.
