"Measurements of Correlations in Nuclear Fission of 238U"
Nuclear fission is one of the most violent processes in nuclear physics, splitting an atomic nucleus and releasing enormous amounts of energy. Despite its importance to nuclear applications and fundamental science, no single theory is able to accurately describe the dynamics of the entire fission process. Modern theories derived from first principles seek to achieve this goal, but require refinement and more data to validate them. In particular, information about correlations between particles produced by fission are of interest.
This talk will discuss measurements of photon-induced fission performed at the High Intensity Gamma-ray Source at Triangle Universities Nuclear Laboratory. A position-sensitive twin ionization chamber was used to measure the energies of both fragments and the direction of their emission and correlations between these properties. The experiment setup, data analysis, and preliminary results will be discussed, with a focus on the evolution of fission observables with excitation energy and comparison to other experimental techniques.
