Radioactive Fusion Experiments for
Understanding Astrophysics and Nuclear Structure

Many of the elements in the periodic table are
synthesized in explosive stellar environments like x-ray bursts, supernovae, and neutron star mergers. X-ray superbursts are rare nucleosynthetic explosions that occur in the outer layers of a neutron star in an interacting binary star system. It is thought that the fusion of very neutron-rich Carbon isotopes is a potential
ignition source for these events. We have conducted an experiment that studied the most neutron-rich carbon-carbon fusion systems to date. The experiment was conducted in 2019 at the Argonne Tandem Linear Accelerator System (ATLAS) facility at Argonne National Laboratory using a radioactive ion beam of 16C. The MUlti-Sampling Ionization Chamber (MUSIC) detector was used as an active-target detector to measure the total fusion cross section of 16C+12C and 16C+13C. The results will be presented along with a discussion of the role that nuclear shell structure plays in the fusion of different carbon isotopes.
