Electron Scattering in the Excitation Region of the Delta Resonance on Nuclei withA=1 to 16

The inelastic electron-scattering cross sections of H, He, Be, C, and O were measured for 730-MeV electrons scattered at 37.1° for energy transfers to the nucleus up to 550 MeV. The nuclear response in the delta region is found to be quite similar for the $A>\mathrm{}1\mathrm{}$ targets. Although the differential cross section per nucleon at the peak of the delta region (380 MeV) is suppressed compared to that of the free nucleon, the area in the 230-550-MeV region is enhanced for the $A>\mathrm{}1\mathrm{}$ targets.
