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 Q-value for radiative capture was also updated in File 3.
Details of these changes are described in Frankel et al. [Fr01].

The COMMARA-2.0 covariances were adopted for Ni-60 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.
S. Kunieda (LANL/JAEA) updated the alpha-particle production
cross sections and energy spectra in MF6MT5 , based on the
improved Iwamoto-Harada model. Oct 22,2004, Holly Trellue remade MF6MT5 using corrected GNASH
code, to fix an earlier bug. Impact is reduced sec. particle prod.
