Neutron induced /sup 238/U subthreshold fission cross section for neutron energies between 5 eV and 3. 5 MeV. [Resonance, resonance clusters, fission widths, 5 eV to 3. 5 MeV]

PDF Version Also Available for Download.

Description

A measurement of the /sup 238/U fission cross section between 5 eV and 3.5 MeV was performed. Included is the identification of 85 resonances or clusters of resonances below 200 keV. Also the fission widths for the 27 resolved class I levels were computed from their fission areas, and a neutron width of 0.005 MeV was estimated for the quasi-class II level in the 721 eV fission cluster. The fission level spacing and cross sections are discussed. 9 references. (JFP)
