Thus, a nuclear reaction must cause a transformation of at least one nuclide to another . If a nucleus interacts with another nucleus or particle and they then separate without changing the nature of any nuclide, the process is simply referred to as a type of nuclear scattering, rather than a nuclear reaction . </P>

Where does the energy released in a nuclear reaction come from
