Structure of Fe70 : Single-particle and collective degrees of freedom

A goal of nuclear science is to achieve an understanding of nuclei and their properties rooted in the fundamental nucleonnucleon interactions while demonstrating predictive power for the shortest-lived species located at the fringes of the nuclear chart. In the quest to extrapolate knowledge to the most neutron-rich systems, including those that may remain beyond experimental reach, much can be learned from nuclei with large neutron excess that clearly display the effects of structural evolution away from the valley of stability. Observables measured for such nuclei provide important extrapolation points toward unknown regions, and their successful modeling offers critical benchmarks for theory. Specifically, the complex interplay between single-particle and collective degrees of freedom in the nuclear many-body system provides unique and interesting experimental and theoretical challenges.
