Current Work
Our current research is focused on a precise measurement 74-77Cu β-decay to better understand the structure of daughter and grand-daughters (Cu → Zn → Ga → Ge) in the decay chain.
These all experiments were performed at the Holifield Radioactive Beam Facility (HRIBF) at Oak Ridge National Laboratory (ORNL). By careful analysis using statistically significant γγ and βγ coincidences, we have pretty extended the decay scheme with new transition lines and energy levels for all daughters and grand-daughters nuclei. We have also readjusted some previously placed transitions due to better understanding of the γγ relationships.
These studies are related to the energy output from nuclear power reactors, the so-called decay heat problem. Understanding the γ rays released by the fission reaction, and then by relaxing daughter nuclei, helps to improve methods to efficiently control next-generation nuclear reactors and their waste management.
