Total-neutron cross sections of the heavy and actinide nuclei /sup 181/Ta, /sup 197/Au, /sup 232/Th, /sup 233/U, /sup 235/U, /sup 238/U, /sup 239/Pu, and /sup 240/Pu were measured from 30 keV to 4.8 MeV. The experimental procedures emphasized a high consistency of the measured data. Systematic uncertainties, excluding those associated with sample masses, were less than or equal to 0.5% and statistical uncertainties were typically less than or equal to 1.0%. At low energies attention was given to resonance self-shielding effects. The experimental results are in good agreement with /sup 232/Th, /sup 233/U, and /sup 238/U data previously reported from this laboratory and at higher energies with the comparable values reported by Foster and Glasgow, excepting /sup 240/Pu which was not studied in the latter work. The measured total-cross-sections were interpreted in terms of a spherical optical model and a deformed coupled-channels model. 31 references.
