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.
The world's most powerful supercomputer is helping resolve conflicting research results that have puzzled scientists for more than a decade, which could also shine new light inside collapsing stars.

Adding or removing neutrons from an atomic nucleus leads to changes in the size of the nucleus. This in turn causes tiny changes in the energy levels of the atom's electrons, known as isotope shifts. Scientists can use precision ...

Atomic nuclei come in different shapes, varying from football-like ("prolate") to pancake-like ("oblate"). Prolate and oblate shapes have different moments of inertia. This is a body's resistance to having its speed of rotation ...
