Nature of problem:
Group-averaged functionals are calculated from evaluted neutron data. The fluctuation error of functionals are calculated in the unresolved energy region and used in the fitting of average resonance parameters to the measured group-averaged cross-sections.
Numerical quadrature of cross-sections given either in tabelled or in parametric form. Generation of stochastic ladders in unresolved resonance region. Statistical evaluation of group-averaged cross- sections. Least-square fitting.
It depends on the representation of neutron data, on the required accuracy, on the width of energy groups and so on.
