  Measurements of inclusive electron-scattering cross sections using hydrogen
and deuterium targets in the region of the Delta(1232) resonance are reported.
A global fit to these new data and previous data in the resonance region is
also reported for the proton. Transition form factors have been extracted from
the proton cross sections for this experiment over the four-momentum transfer
squared range 1.64 < Q^2 < 6.75 (GeV/c)^2 and from previous data over the range
2.41 < Q^2 < 9.82 (GeV/c)^2. The results confirm previous reports that the
Delta(1232) transition form factor decreases more rapidly with Q^2 than
expected from perturbative QCD. The ratio of sigma _n \sigma_p in the
\Delta(1232) resonance region has been extracted from the deuteron data for
this experiment in the range 1.64 < Q^2 < 3.75 (GeV/c)^2 and for a previous
experiment in the range 2.4 < Q^2 < 7.9 (GeV/c)^2. A study has been made of the
model dependence of these results. This ratio sigma_n\sigma_p for \Delta(1232)
production is slightly less than unity, while sigma_n\sigma_p for the
nonresonant cross sections is approximately 0.5, which is consistent with deep
inelastic scattering results.
