WebFeb 3, 2011 · The fission cross sections of 247Cm, 254Es, and 250Cf are measured with the Rensselaer intense neutron spectrometer from 0.1 eV to 80 keV. The cross sections are normalized to the 235U ENDF/B-V... Each fission of a parent atom produces a different set of fission product atoms. However, while an individual fission is not predictable, the fission products are statistically predictable. The amount of any particular isotope produced per fission is called its yield, typically expressed as percent per parent fission; therefore, yields total to 200%, not 100%. (The true total is in fact slightly grea…

WebFission yields from fast-neutron-induced ssion were calculated by a summa- tion method [WA99] giving weighted average parameter values for those model parameters that are energy dependent. Equations derived for low-energy ssion were used (Tables 1 and 2, pp. 12 & 29) because most of the increments that were summed had E* values <8 MeV. WebA radiochemical investigation has been made of the fission yield curve for the spontaneous fission of Cf 252.One source of 1× 10 6, another of 2× 10 7, and a third of 7× 10 7 fissions per minute were used to obtain the data. Thirty-six radioactive nuclides between mass numbers 77 and 166 were separated, identified, and their fission yields … WebNuclear fission is the splitting of the nucleus of an atom into two or more separate nuclei accompanied by the release of a large amount of energy. The reaction can be induced by a nucleus absorbing a neutron, or it can occur spontaneously, because of the unstable nature of some of the heavy isotopes. song miss polly had a dolly
