The absolute value of the total neutron cross section of U/sup 233/ was measured at neutron energies between 0.000818 ev and 0.0818 ev for two types of samples, a metallic foil and D/sub 2/O solutions of uranium nitrate. Balanced solutions of U/sup 233/O/sub 2/(NO/sub 3/)/sub 2/ and U/sup 238/O/sub 2/(NO/sub 3/ )/sub 2/ were used to determine the difference between the total cross sections of U/sup 233/ and U/sup 238/. This value when combined with the relatively small known value of the total cross section for U/sup 238/ gives sigma /sub T/(U/sup 238/) = 587 plus or minus 5 barns at 0.0253 ev. The measurements on the metallic U/sup 233/ foil agreed with the measured total cross section determined from the liquid solution data to better than 1%, yielding sigma /sub T/(U/sup 233/) = 586 plus or minus 2 barns at 0.0253 ev.
