An Investigation of the Nuclear Continuum in the Fissionable Nucleus U238 with 87.5 MeV Electrons.
Abstract
Electroexcitation of U238 between 5 and 40 MeV was accomplished using 87.5 MeV electrons. Data were recorded at scattering angles of 45, 60, 75, and 90 deg and an analysis was made using DWBA calculations and the hydrodynamic model. The results agree with the known positions, widths and cross sections of the Giant Dipole Resonances at E sub x = 10.9 MeV and 14.0 MeV thus confirming the validity of our evaluation method. In addition, isoscalar and isovector E2 resonances and an isovector E3 resonance were found at 9.9 MeV (gamma = 2.9), 21.5 MeV (gamma = 4.9), and 28.4 MeV (gamma = 8.1), exhausting 39%, 50% and 88% of the respective EWSR. Although isospin cannot be determined from (e,e'), delta T assignments were based on microscopic and macroscopic considerations. (Author)
