Update the evaluated independent and cumulative fission yield data for U-235,U-238, and Cf-252.
Specific Objectives
Compile all available experimental data on independent and cumulative fission yields, measured total kinetic energies and total neutron yields, mass and charge-yield data.
Assess experimental data at all available incident energies to establish consistency and characterize experimental uncertainties.
Evaluate the available experimental data and provide recommended fission yield data with associated uncertainties for U-235, U-238, Cf-252 (and possibly for Pu-239, Pu-241).
Improve models and systematics to provide fission yield data for masses and incident energies where experimental data are not available.
Develop formats to store new information such as covariances and incident energy dependencies beyond the standard thermal, fast and 14 MeV energies.
Validate the new evaluated fission yield data files against valid benchmark measurements and integral data.
