Nuclear Physics

Nuclear physics is the branch of physics and nuclear science that analyses atomic nuclei and their structure, along with the study of other types of nuclear matter. Nuclear physics must not be misunderstood with atomic physics, which studies the atomic element as a whole, inclusive of the electrons.
