Theoretical and experimental determinations of the cadmium correction factor FCd have been made for various thicknesses of indium foils in an isotropic epithermal neutron flux. It was found that for indium foils with 0.040-in. cadmium covers FCd varied slightly with foil thickness and reached a maximum value of 1.123 for thicknesses greater than 90 mg/cm2.
