Abstract
The giant-resonance region between 8 and 12 MeV measured by (e, e') in (208)Pb is disentangled into narrow lines (I,& 4 keV) and broad resonances (I,& 1800 keV). The narrow lines at 10.07, 10,60, and 11.37 MeV have an E2 angular distribution, and assumption of b, T = 1 for them explains controversial
experimental results of electromagnetic and hadronic experiments. The new analysis makes an assignment for the 8.9-MeV resonance other than monopole difficult to understand.
