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.
Nuclear theorists at Brookhaven National Laboratory and Argonne National Laboratory have successfully employed a new theoretical approach to calculate the Collins-Soper kernel, a quantity that describes how the distribution ...

Protons and neutrons–known collectively as nucleons–are both the building blocks of matter, but one of these particles has received a bit more attention in certain types of nuclear physics experiments.

Why are there atomic clocks but no nuclear clocks? After all, an atom's nucleus is typically surrounded by many electrons, so in principle it should be less susceptible to outside noise (in the form of light). A nucleus, ...
Recent experiments at CERN have shed new light on the nuclear properties of atomic nuclei (i.e., the central regions of atoms accounting for most of their mass). A key objective of recent research into atomic nuclei has been ...
The search for new elements comes from the dream of finding a variant that is sufficiently stable to be long-lived and not prone to immediate decay. There is a theory in nuclear physics about an island of stability of superheavy ...

Nuclear fission—when the nucleus of an atom splits in two, releasing energy—may seem like a process that is fully understood. First discovered in 1939 and thoroughly studied ever since, fission is a constant factor in ...

Neutrons are among the basic building blocks of matter. As long as they are part of a stable atomic nucleus, they can stay there for arbitrary periods of time. However, the situation is different for free neutrons: They decay—after ...

The atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to reproduce all the properties of ...
