Maeck, W. J.

The relative isotopic abundances and the fission yields for over 40 stable and long-lived fission products from /sup 235/U fast fission correlate well with neutron energy. Only mass spectrometric data were used in this study. For many nuclides, changes of only a few percent in the relative isotopic abundance or the fission yields over the energy range of thermal to 1 MeV are easily discernable and significant. The neutron energy index used in this study is the /sup 150/Nd//sup 143/Nd isotopic ratio. The results of this correlation study are compared to the US Evaluated Nuclear Data File (ENDF) fast fission yield compilation. Specific discrepancies are noted.
