Book Description
This Ph. D. dissertation describes a measurement of the change in mass distributions and average total kinetic energy (TKE) release with increasing incident neutron energy for fission of 235U and 238U. Although fission was discovered over seventy-five years ago, open questions remain about the physics of the fission process. The energy of the incident neutron, En, changes the division of energy release in the resulting fission fragments, however, the details of energy partitioning remain ambiguous because the nucleus is a many-body quantum system. Creating a full theoretical model is difficult and experimental data to validate existing models are lacking. Additional fission measurements will lead to higher-quality models of the fission process, therefore improving applications such as the development of next-generation nuclear reactors and defense. This work also paves the way for precision experiments such as the Time Projection Chamber (TPC) for fission cross section measurements and the Spectrometer for Ion Determination in Fission (SPIDER) for precision mass yields.

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.
