Threshold inelastic electron scattering from the proton at high momentum transfers.

Cross swtions for threshold electron scattering from the proton have been measured in the missing-mass squared region M2 < W2 < 2 (GeV) 2 and the four-momentum transfer squared region 6< Q2 <30 (GeV/c)2. Scaling of the extracted values of the structure function F2 = VW2 is examined in the variables z, ~, and W2. The best scaling is found for the quantity Q6F2, which is found to be linearly proportional to (W2 – W~~), where ~th = M + Mm.
