Book Description
The primary aim of the present study was to put fission yields from U235 on a quantitative basis. The absolute fission yield of a convenient reference nuclide, 12.8d Ba140, was measured in a more direct manner than had previously been done. Fission yields in U235 and U238 were compared for a number of nuclides to determine whether or not the fission yields in natural uranium in a thermal neutron reactor might be influenced appreciably by fast fission of U238. As a result of this last experiment it was noted that the fission yield curves of U235 and U238 have significantly different shapes.

Book Description
Delayed neutron studies have been made in the Experimental Breeder Reactor (EBR), using a conventional sample transfer system and a neutron counter comprised of BF3 tubes in a graphite geometry. Samples of U-235, U-233, U-238, Pu, and Th were irradiated in a fast flux; samples of U-235, U-233, and Pu were irradiated in a thermal flux.

Book Description
Experimental measurements of the gamma-ray pulse height distributions due to the products of fast-neutron-induced fission of Uranium-235 and Uranium-238 are presented. The measurements were made at nine selected times after fission from 15 minutes to 3 days. Irradiation times and counting intervals were chosen to minimize saturation and decay effects. The experimental data were used to calculate 100 energy bin distributions of the absolute number of photons/fission-sec. by means of absolute calibrations of the collimated NaI(T1) detector. The number of fissions in each sample was determined radiochemically. Machine computation was used extensively.
