%'e report high resolution measurements of inelastic electron scattering to all narrow normalparity states of '60 up to 12.05 MeV, which include states with J"(E"MeV): 0~+(6.049),The measurements were performed primarily at 90' and 160' and span momentum transfers between 0.6 and 2.6 fm '. Improved line shape fitting techniques have been developed. These are the first electron scattering measurements for the 4~+ state and of second form-factor maxima for several states. The form factor for excitation of the 2+2 state is strikingly different from that of the other 2+ states and indicates a transition density peaked in the interior. Transition charge densities were extracted from a combined data set that includes earlier electron scattering data renormalized to a recent analysis of elastic scattering from ' O. Comparisons have been made with several structure models, including the Brown-Green model, the weak-coupling model, a Pun shell model, and the tetrahedral alpha-cluster model.

The reaction n C{e,e'p) in the dip region (o> = 200 MeV, q = 400 MeV/c) has been measured in parallel kinematics for missing energies up to 160 MeV. A coincidence yield considerably larger than that expected for a one-body reaction process is observed, though the one-body contribution from p-and s-shell knockout is also present. A uniform continuum strength extends from beyond the p shell to the highest measured missing energies. This continuum strength is the dominant contribution to the (e,e f p) reaction process in the dip region.PACS numbers: 25.30.Fj

Double di8'erential cross sections for inelastic electron scattering from He have been measured at bombarding energies between 279 and 725 MeV. The longitudinal and transverse response functions were obtained for constant momentum transfer between 300 and 500 MeV/c. Plane-wave impulse approximation calculations overestimate the longitudinal response and produce fair agreement with the transverse part. The Coulomb sum is determined and compared with exact calculations. Within the experimental error the data exhaust the sum rule; this provides a 6rst measurement of ground-state correlations.

Longitudinal response functions for 3 H and 3 He have been obtained from inclusive electron scattering cross sections, for 200 <
