Decay mode



In physics, the decay mode describes a particular way a particle decays. For radioactive decay (the decay of nuclides) the decay modes are: * alpha decay (emission of a Helium-4 nucleus). * beta decay (emission of an electron) * beta decay (emission of a positron) * electron capture * proton emission * spontaneous fission Typically one decay mode predominates for a particular nuclide. branching ratio are used when this is not true. A decay will sometimes leave the nucleus in an excited state. When long lived these states are called isomeric states. These isomers will typically decay to the ground state of the nuclide, but unlike the radioactive decays above these isomeric transitions do not change one nuclide into others. These decays are: * Emission of a high-energy photon (gamma emission) * Ionizing the atom (internal conversion) Nuclear physics Nuclear chemistry
