Many-Body Nuclear Dynamics Group: Research

The goal of this experiment was to examine both the decay of excited and deformed projectile-like nuclei formed in peripheral heavy-ion collisions as well as the possible neutron enrichment of the low density mid-rapidity (neck) zone. The experiment was a collaboration between groups from Universite Laval, Texas A & M University, and Indiana University. In this experiment, the new detector array FIRST was commissioned. Our first results from this experiment (Theriault et al.) reveal that a measurable neutron-enrichment of low-density nuclear matter is observed. This enrichment can be related to the density dependence of the symmetry energy of nuclear matter.
Typical pulser spectrum used to monitor the electronic stability
Location of three peaks in the pulser spectrum as a function of time that demonstrate the electronic stability is of the order of 0.5%
