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 & Q & 7 (GeV/c) . The forward-angle data are in good agreement with a recent calculation. Both the data and the calculation show scaling behavior for F2(g, Q~)=vs(g, Q2) at high Q for fixed values of the Nachtmann variable g. The ratio R =oL /trr has been extracted for 1.75 &Q &5 (GeV/c) and is found to decrease with Q2 to a value consistent with zero at the highest Q~.

The proton elastic electric and magnetic form factors, GEM and G’bfP(Q2), have been separately measured in the range Q” =1.75 to 8.83 (GeV/c)2, more than doubling the Q3 range of previous data. Scaled by the dipole fit, Go(Q2), the results for Gnlp(Q2)//+G~(Q2) d ecrease smoothly from 1.05 to 0.91, while G~p(Q~)lcdQ~) is consistent with unity. Comparisons are made to QCD Sum L-eRule, diquark, constituent quark, and VMD models, none of whic,h agree with all of the new data. The ratio Q2F2/Fl approaches a constant value for Q2 > 3 ( GeV/c)2. --p;. .- -- 2
