Fission yield curve

WebFission product yield measurements have played an important part in the study of fission since its discovery. The main interest initially was the general shape of the fission … WebThe spontaneous fission yield curve peaks were found to be much sharper than those associated with other fission processes. Evidence was found for fine structure in the fission yield curve at mass 132, possibly connected with preferential formation of spontaneous fission fragments containing 50 protons and 82 neutrons.

WebThe fission product yield for 235 U, normalized to 1000 fissions are given in Fig. 1.38 at two different energies. It may be noticed that X-axis is in linear scale and Y-axis is in log … 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. Because of the stability of nuclei with even numbers of protons and/or neutrons the curve of yield against element is not a smooth curve. It tends to alternate. In general, the higher the energy of the state that undergoes nuclear fission, the more likely a symmetric fission is, hence as the neutron energy … See more Nuclear fission splits a heavy nucleus such as uranium or plutonium into two lighter nuclei, which are called fission products.

WebMar 9, 2012 · The Wikipedia description of the fission process and the fission product yield curve is helpful. Look at the red curve for the fission of 235 U, and you can see the favored mass distribution. The table below the curve shows some of the expected fission products, arranged from favored fission products to less likely products. 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…
