Nuclear physics is a research area focused on the structure, dynamics, and interactions of atomic nuclei and their constituent nucleons, governed primarily by the strong and weak nuclear forces within the framework of quantum many-body and quantum field theories. It investigates phenomena such as nuclear binding, excitations, decay modes, and reactions, including fission, fusion, and nucleosynthesis. The field encompasses experimental and theoretical studies of stable and exotic nuclei, hadronic matter under extreme conditions, and the emergence of collective behavior from underlying nucleon–nucleon interactions, often employing accelerators, detectors, and advanced computational methods to probe fundamental properties of nuclear systems and refine effective interaction models.
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 ...
