Neutron-rich nuclei are atomic nuclei that contain significantly more neutrons than protons compared to their stable or naturally occurring counterparts. Due to this imbalance, they are often unstable and tend to undergo radioactive decay in pursuit of greater stability. Studying these exotic nuclei provides valuable insights into nuclear structure at the limits of existence. Such investigations are key to addressing fundamental questions in nuclear physics: Where do atoms and their nuclei originate? How are atomic nuclei formed, structured, and influenced by the fundamental forces? And what are the scientific and practical applications of these nuclei?
