1009019	009_F_019	ENDF/B-VII	ENDF/B-VII: Only high quality covariance data were migrated from ENDF/B-VI.8 (M. Herman) For the remaining reaction channels, namely elastic scattering and radiative capture, covariances were estimated at LANL based on a brief analysis of experimental data and their agreement with the ENDF/B-VII.0 central values.		ENDF/B-VI MOD 2	Revision (S.C.Frankle, R.C.Reedy, P.G.Young, J. Campbell, R. Little (LANL) August, 2001 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 200 keV. The Q-value for radiative capture was also updated in File 3. Details of these changes are described in Frankle et al. [Fr01]. Note that the radiative capture data were changed from pure continuum data in MF=6, MT=102, to discrete plus continuum data in MF=12,14,15, MT=102. The continuum spectra above 200 keV are unchanged from MOD 1, but the yields were modified slightly in MF=12,MT102 for energy conservation. The thermal neutron photon production spectrum is comprised of 168 discrete photons. Two negative probability values (MF=6 MT=28 and MF=6 MT=107) were changed (update of August 2001): -5.08530e-12 -> 5.08530e-12 and -1.3263e-7 -> 1.3263e-7
