Inelastic electron scattering from /sup 208/Pb at 180/sup 0/

Inelastic cross sections for 180/sup 0/ electron scattering from /sup 208/Pb have been measured at incident energies of 40.5, 50.4, 60.3, and 75.2 MeV. Transverse electric form factors have been determined for the 3/sup -/ state at 2.614 MeV, the 5/sup -/ states at 3.198 and 3.708 MeV, the 2/sup +/ states at 4.085 and 6.21 MeV, the 4/sup +/ state at 4.323 MeV, and the 6/sup +/ state at 4.422 MeV. The results for these natural parity states are compared to the predictions of an incompressible, irrotational current model, and of a particle-hole model. All transverse electric form factors show strong contributions from intrinsic magnetization currents. Transverse form factors were obtained for the proposed 1/sup +/ state at 4.84 MeV, for the group of 1/sup +/ states at 7.48 MeV, and for several proposed 2/sup -/ states. A search for M1 transition strength was made up to excitation energies of 19 MeV. The future of electron scattering as a tool for probing M1 strength in /sup 208/Pb is discussed.
