Abstract

Neutron-rich isotopes are extremely important for the improved understanding of nuclear structure and reactions. The neutron drip line has currently not been probed past a proton number of 8, and knowledge of where it lies helps answer the question of what combinations of nucleons can form a stable nucleus. Neutron-rich nuclei form exotic structures such as neutron skins and halos, and are not accurately described by current models such as the shell model. The improvement of current models and development of new models for describing the behavior of neutron-rich nuclei is essential for the field of nuclear physics. In my review paper, I will investigate our current knowledge about how nuclei are organized, what nucleon combinations can form a bound nucleus, and how those properties relate to structure and dynamical phenomena in the universe.
