Nuclear structure & decays is a research area in nuclear physics that investigates the internal configuration, quantum states, and dynamical behavior of atomic nuclei, along with the mechanisms by which unstable nuclei transform via radioactive decay. It encompasses the development and application of models such as shell, collective, and mean-field theories to describe nucleon distributions, energy levels, and transition probabilities, and studies decay modes including alpha, beta, gamma, and fission processes. The field integrates experimental spectroscopy, reaction studies, and advanced many-body calculations to elucidate nuclear forces, shape coexistence, isomerism, and the evolution of structure far from stability, informing both fundamental theory and applications in astrophysics and nuclear technology.
Scientists from Massey University in New Zealand, the University of Mainz in Germany, Sorbonne University in France, and the Facility for Rare Isotope Beams (FRIB) discuss the limit of the periodic table and revising the ...

Atomic nuclei are made of nucleons (like protons and neutrons), which themselves are made of quarks. When crushed at high densities, nuclei dissolve into a liquid of nucleons and, at even higher densities, the nucleons themselves ...
