Prompt Neutron Fission Spectrum Mean Energies for the Fissile Nuclides and sup 252 Cf

摘要

The international standard for a neutron spectrum is that produced from the spontaneous fission of sup 252 Cf, while the thermal neutron induced fission neutron spectra for the four fissile nuclides, sup 233 U, sup 235 U, sup 239 Pu, and sup 241 Pu are of interest from the standpoint of nuclear reactors. The average neutron energies of these spectra are tabulated. The individual measurements are recorded with the neutron energy range measured, the method of detection as well as the average neutron energy for each author. Also tabulated are the measurements of the ratio of mean energies for pairs of fission neutron spectra. 75 refs., 9 tabs. (ERA citation 10:038294)
