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 > 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.

Electron scattering experiments have been performed on the deformed nuclei 5 Sm, Sm, Fr, 7 Yb Th, and U at momentum transfers between 0.5 fm and 1.3 fm l The cross sections for the 0, 2+, and 4+ rotational states of these nuclei have been obtained and, together with other information on the electromagnetic properties of these nuclei, these data lead to information about the deformed shapes. The shapes of '6~Er and '~Y b are quite different from the shapes of 5 Sm and 4Sm and require a varying skin thickness. The Sm isotopes require a constant skin thickness. Results are presented for po(r), p2(&), and p4(r).NUCLEAR REACTIONS~Sm(e, e') ls4Sm(e, e'), 6 Er(e, e') Yb(e, e') Th( e, e'), and~U(e, e'); measured cross sections for ground state and first excited states for 0.5 «q eff~1 .2 fm
