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. WebThe curves for the fission of the later actinides tend to make even more shallow valleys. In extreme cases such as 259 Fm, only one peak is seen. Yield is usually expressed …
