The Probability Table Method for Treating Unresolved Neutron Resonances in Monte Carlo Calculations
TL;DR: The use of Monte Carlo calculations in reactor criticality and shielding problems requires cross section data sets which are properties of the individual isotopes rather than group averaged sets as mentioned in this paper, which is not a suitable approach.
