Fission Product Yields from 6-9 MeV Neutron Induced Fission of 235U and 238U.

摘要

The yields of 28 mass chains have been measured for fission of U235 and U238 induced by neutrons at four different energies from 6.0 to 9.1 MeV. This is the first experimental measurement where sufficient energy resolution was obtained to observe the effect of the onset of second chance fission in the case of symmetric fission. The Ag111 results are compared with measurements at other neutron energies and with previous theoretical predictions. Several of the nuclide results are presented in graphical form and all nuclide are presented in tabular form, as a function of neutron energy. The mass chains measured range from 84 to 156, and their half-lives range from 18 minutes to 30 years. (Author)
