A method is given for obtaining corrections to cadmium ratio measurements for flux depressions in the foil and flux perturbation effects in order that the result may be used in descriptions of the reactor neutron-energy spectrum. The effects are accounted for by introducing combined flux-depression and flux-perturbation factors, one for each of the three spectral shapes: (a) h/ sup M/(X) for the Maxwellian flux; (b) h/sup e/(X) for the epithermal flux, E > mu kT; and (c) h/sub cd/(X) for the resonance flux, E > E /sub cd/, where X is the foil thickness. The values of H/sup M/(X) and H/sup e/(X) were determined experimentally with gold foils. These values are given as a function of the foil thickness from 0 to 100 mg/ cm/sup 2/ (B O.G.)
