2. FISSION PRODUCT YIELDS ^[*]

TABLE 1 lists independent fission product yields (England and Rider 1994) per 100 fissions for the most important fissionable nuclides. For ²³⁵U thermal, fast neutron (fission spectrum), and high-energy neutron (14 MeV) induced, for ²³⁸U fast neutron induced, for ²³⁹Pu thermal neutron induced, and for ²⁵²Cf spontaneous fission data are provided. Fission yield measurements from the literature and calculated charge distributions were used to produce this recommended set of yields for the fission products. The full data set can be found in the report by England and Rider (1994), which also serves as the primary documentation for the second evaluation of fission yields in the nuclear data library ENDF/B-VI released in 1993.
