The deformed, fissionable nucleus 238U was studied with inelastic scattering of 87.5 MeV electrons between 5 and 40 MeV excitation energy, at scattering angles of 45°, 60° 75° and 90°. Resonance cross sections extracted from the spectra were compared with DWBA calculations using the Tassie (Goldhaber-Teller) model. The results agree with the known positions, widths and cross sections of the two branches of the giant dipole resonance at Ex = 10.9 MeV and 14.0 MeV, thus confirming the validity of the evaluation
method. In addition, isoscalar and isovector E2 resonances and an isovector EJ resonance were
found at 9.9 MeV (r = 2.9), 21.5 MeV (r = 4.9) and 28.4 MeV (r = 8.1), exhausting 40%,
50% and 90% of the respective EWSR. Although isospin cannot be determined from (e,e'), ∆T
assignments were based on microscopic and macroscopic considerations.National Science FoundationNaval Postgraduate School Research Foundatio
