Cluster Structure and Three-Body Decay of ¹⁴C

Recent model calculations with most advanced methods for cluster states have shown the need of experimental data to probe the structure of light exotic nuclei, including those with α-clustering, such as ¹⁴C. The prototype Active Target Time Projection Chamber (pAT-TPC) allows us to investigate these types of structures. This type of detector allows access to the excitation function at all energies and angles with a single beam energy. The measurement was carried out by resonant alpha-scattering of a ¹⁰Be beam at 40 MeV delivered by the TwinSol facility at the University of Notre Dame. This type of experiment measures resonances in ¹⁴C that can be compared to the models using R-Matrix reaction theory. Additionally, using a Dalitz-type analysis, three-body decays can be analyzed to determine probabilities of "democratic" and "sequential" decay.  Results will be presented focusing on new high-energy resonances and three-body decay analysis.
