Session 14: Nuclear Structure, Reactions and Dynamics
- JJ van Zyl (Stellenbosch University)
The Isoscalar Giant Monopole Resonance (ISGMR) is a collective excitation mode of the atomic nucleus, first discovered in 1977. Our current understanding of the ISGMR in stable nuclei relies heavily on experimental investigations conducted at the Texas A&M University (TAMU) Cyclotron Institute and the Research Center for Nuclear Physics (RCNP) over the past thirty years. These investigations...
Studying exotic nuclei exhibiting an extreme ratio of neutrons to protons is one of the primary means for better understanding of fundamental nuclear properties, which is crucial to comprehend the formation and existence of heavy elements in our universe. Nevertheless, it is well understood that nuclei from certain regions on the chart of nuclei, e.g., neutron-rich actinides, will not be...
Nuclear reactions play a critical role in probing the properties of atomic nuclei, production of elements in astrophysical environments, as well as national security applications. For example, a class of reactions known as ‘transfer reactions’ are useful in determining spins, parities, and spectroscopic factors for specific nuclear states. In particular, deuteron-induced transfer reactions on...
The $^{58}$Ni+$^{58}$Ni reaction was measured using the INDRA-FAZIA apparatus at three different energies: 32, 52, and 74 AMeV. In peripheral and semi-peripheral collisions, two main distinct reaction channels, one associated with the QP remnant and the other with the QP breakup channel, were identified. The analysis was conducted as a function of incident energy and collision centrality. In...
Exotic nuclei are typically produced via projectile fragmentation or projectile fission at relativistic energies, or through complete fusion reactions at near-Coulomb barrier energies. These production methods, along with the available beam intensities, define the current boundaries of the chart of nuclides. However, theoretical predictions suggest that several thousand additional isotopes may...
Multinucleon transfer (MNT) reactions induced by 40,48Ca ions on Au target have been studied at 400 MeV bombarding energy. Projectile-like fragments have been identified in nuclear charge, angular and kinetic energy distributions and inclusive cross sections were measured. Two groups of products were identified in: 1) deep-inelastic products, the maximum yield of these products was at...
The occurrence of collective excitations is one of the key and noticeable spectroscopic characteristics of the atomic nucleus. Although the measurement of the B(E2;$2_1 \rightarrow 0_1$ ) transition probabilities is very useful for studying the evolution of collectivity along isotopic or isotonic chains, a deeper understanding of the collective behavior of a given nucleus can be gained by...
