The nuclear response in the delta region is found to be quite similar for the A>1 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>1 targets.

The shapes of the energy spectra, the angular distributions, and the ratios of cross ...
