Sensitivity of uranium spectra to inelastic matrix perturbation

The capability for utilizing interactive graphics computing for direct data adjustment has been extended to facilitate studies of inelastic matrices, and has been applied to identify the type of data modification appearing most likely to resolve experiment-theory discrepancies. While this type of investigation does not yield a unique new data set, it does lead to a recommendation that evaluations for new ENDF/B files for uranium emphasize reductions in transfers from the MeV range to low energies
