Results from calculations using a 2021-energy-group cross section library with sufficient energy definition in the lower energy range to resolve the known resorances in /sup 239/Pu and /sup 235/U are compared with flat-plate resorance self-shielding experimental data. The results are somewhat ambiguous. The lower energy ranges appear to agree better with experimental data for small areal densities, but disagree more as the areal density increases.
