The cumulative fission yields of the four nuclides 95Zr, 99Mo, 144Ce and 147Nd are key parameters in estimating the effects from nuclear tests and for post-detonation nuclear forensics in general. Driven particularly by differences in the fission yields from 239Pu(n,f) that have been in use by LLNL and LANL over the years, an intensive effort has been undertaken to evaluate the current state of our knowledge of these yields and to provide a basis for projecting yields to those applicable to forensics. The neutron spectrum producing fission in the Jezebel critical assembly (< En > ~ 1.9 MeV) may be taken as a reasonable reference. It is desired to know the cumulative fission yields to a total uncertainty (1σ) of ± 2.5%.
