Compound nucleus reaction

WebIn nuclear physics and nuclear chemistry, a nuclear reaction is a process in which two nuclei, or a nucleus and an external subatomic particle, collide to produce one or more new nuclides.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 … WebCompound Nucleus a nuclear system formed in the course of a nuclear reaction by the combination of the incident particle with the target nucleus. A compound nucleus is unstable and decays after a short period into final reaction products.

WebNuclei are located in atoms that are themselves in continual motion owing to their thermal energy. As a result of these thermal motions, neutrons impinging on a target appear to the target’s nuclei to have a continuous spread in energy.
