Correlations of the Independent Fission Product Yields of Different Isotopes

The independent fission product yields obtained from the fast fissions of ²³²Th, ²³³U, ²³⁵U, ²³⁸U, ²³⁹U, ²⁴⁰Pu, and ²⁴¹ Pu were found to be correlated to the 2Z-N values of these isotopes. Examples of these correlations are presented. In these examples, the chain yields of ¹³⁵Xe and ¹⁴⁹Sm, the important isotopes in the dynamics of nuclear reactors, are included. The correlations obtained can serve to predict the independent fission product yields from important actinides that have no experimental results so far. These correlations can also serve to point out errors in current evaluated yields.
