摘要：

Transition form factors have been extracted from inclusive electron-scattering data in the Q2 range 1 to 10 GeV2/c2 for the DELTA(1232) and second resonance, which is dominated by the S11(1535). The form factor for the second resonance appears to approach a Q-4 dependence expected from leading-order perturbative QCD, while the form factor for the DELTA(1232) decreases faster than Q-4, which would be expected when nonleading processes are dominant.
