Download Sup 238/U Neutron-induced Fission Cross Section for Incident Neutron Energies Between 5 EV and 3. 5 MeV. Book in PDF, ePub and Kindle
A measurement of the /sup 238/U neutron-induced fission cross section was performed at the ORELA Linac facility in the neutron energy range between 5 eV and 3.5 MeV. The favorable signal-to-background ratio and high resolution of this experiment resulted in the identificaion of 85 subthreshold fission resonances or clusters of resonances in the neutron energy region between 5 eV and 200 keV. The fission data below 100 keV are characteristic of a weak coupling situation between Class I and Class II levels. The structure of the fission levels at the 720 eV and 1210 eV fission clusters is discussed. There is an apparent enhancement of the fission cross section at the opening of the 2/sup +/ neutron inelastic channel in /sup 238/U at 45 keV. An enhancement of the subthreshold fission cross section between 100 keV and 200 keV is tentatively interpreted in terms of the presence of a Class II, partially damped vibrational level. There is a marked structure in the fission cross section above 200 keV up to and including the plateau between 2 and 3.5 MeV. 11 figures and 6 tables.

Download 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]. Book in PDF, ePub and Kindle
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).
