Kawano (LANL) MF=3 MT=107,22,112; MF=6 MT=5 alpha production only Talys-1.2 calculations of alpha production Modified MF=3 MT=107 at energies below 11 MeV and reduced MF=3 MT=22 contribution to better agree with experimental data HA08, KE96, GL97, GU95, GO92, FE99 and MA97; MF=3 MT=3 & MF=3 MT=2 adjusted to absorb above changes	Aug-2011, BNL, S. Hoblit The COMMARA-2.0 covariances were adopted for Ni-58 in the fast neutron region. Here, like in the Cr and Fe materials, the starting point was the ENDF/B-VI.8 covariances which resulted from an evaluation by the highly experienced ORNL group. Then, these data were subject to a dispersion analysis, leading to certain modifications of uncertainties, while correlations were left unchanged. In the resonance region, a MF33/LB=5 section was added to the covariances for elastic and total in the upper range of the resonance region (6-775 keV) to account for the uncertainty in the scattering radius R'. The uncertainty in R' was taken from the Atlas of Neutron Resonances [1] and propagated to the elastic cross sections using the energy bins of the AFCI COMMARA-2.0 processed files. To fully account for the uncertainty as given in COMMARA-2.0, an additional 4% MF33/LB=1 section was added to elastic from 248-775 keV and 8% LB1 section was added to capture from 50-775 keV.

Young (LANL) The secondary gamma-ray spectrum for radiative capture (MF 12, MT 102) has been updated for new experimental data at incident neutron energies up to 1 keV. The MF=12, MT=102 yields above 1 keV were adjusted slightly to force energy conservation. The Q-value for radiative capture was also updated in File 3. Details of these changes are described in Frankel et al. [Fr01].		S. Kunieda (LANL/JAEA) updated the alpha-particle production cross sections and energy spectra in MF6MT5 , based on the improved Iwamoto-Harada model. [Sep 3,2011] Oct 22,2004, Holly Trellue remade MF6MT5 using corrected GNASH code, to fix an earlier bug. Impact is reduced sec. particle prod. Covariance data: only MF/MT=33/16 migrated from ENDF/B-VI.8 (M. Herman)
