Resonance Integral Calculations for U²³⁸ Lattices

Resonance integrals computed by the method of Chernick and Vernon are compared with precise results from a series of Monte Carlo calculations with very large numbers of histories. The range of applicability of the method of Chernick and Vernon is exhibited by this comparison. Some simplifications are made in the method of presentation of the resonance integral results so that the correlation among single lumps and lattices of various compositions is improved.
