branching


branching

      radioactive disintegration of a particular species of unstable atomic nucleus or subatomic particle that occurs by two or more different decay processes. Some nuclei of a given radioactive species may, for example, decay by ejecting an electron (negative beta decay) and the rest by ejecting an alpha particle (alpha decay). Thus, 64 percent of any collection of atoms of bismuth-212 decay to polonium-212 by ejecting electrons, while the rest (36 percent) decay to thallium-208 by ejecting alpha particles. The fraction decaying in a particular way is called the branching fraction or branching ratio.
