nuclear reaction definition


A reaction that changes the number of protons or neutrons in the nucleus of an atom. There are several kinds of nuclear reactions, including the fragmentation of large nuclei into smaller ones (nuclear fission), the building up of small nuclei into larger ones (nuclear fusion), and changes begun by collisions with elementary particles or other nuclei (as in particle accelerators).
