Nuclear structure is the study of the arrangement and properties of atomic nuclei, the central part of an atom that contains protons and neutrons. This field of research involves studying the organization of nucleons within the nucleus, as well as their interactions and properties. Scientists in this field seek to understand the behavior of nuclear particles, such as their energy levels, spin, and shape, as well as the forces that hold them together. This research is important for understanding nuclear reactions, nuclear decay, and the properties of different elements.
