Abstract
It is demonstrated that the sensitivities approach to cross-section adjustment unavoidably leads to adjustment by least squares. The relative weight of integral with respect to differential data is introduced and the advantage of its use as a free parameter is discussed. As an illustration, the proposed procedure is applied to the ENDF/B-3 library and several Los Alamos critical assemblies.
