WebSep 11, 2009 · The kinetic energy of the proton (or nucleus), electron and anti-neutrino comes from the difference in mass between the products and the neutron. The partition … The Q value is defined as the total energy released in a given nuclear decay. In beta decay, Q is therefore also the sum of the kinetic energies of the emitted beta particle, neutrino, and recoiling nucleus. (Because of the large mass of the nucleus compared to that of the beta particle and neutrino, the kinetic energy of the … See more In nuclear physics, beta decay (β-decay) is a type of radioactive decay in which a beta particle (fast energetic electron or positron) is emitted from an atomic nucleus, transforming the original nuclide to an isobar of … See more In β decay, the weak interaction converts an atomic nucleus into a nucleus with atomic number increased by one, while emitting an electron ( e ) and an electron antineutrino ( ν e). β decay generally occurs in neutron-rich nuclei. The generic equation is: See more In all cases where β decay (positron emission) of a nucleus is allowed energetically, so too is electron capture allowed. This is a process during which a nucleus captures one of its atomic electrons, resulting in the emission of a neutrino: See more The two types of beta decay are known as beta minus and beta plus. In beta minus (β ) decay, a neutron is converted to a proton, and the process creates an electron and an See more Discovery and initial characterization Radioactivity was discovered in 1896 by Henri Becquerel in uranium, and subsequently observed by Marie and Pierre Curie See more In β decay, or positron emission, the weak interaction converts an atomic nucleus into a nucleus with atomic number decreased by one, while emitting a positron ( e ) and an electron neutrino ( ν e). β decay generally occurs in proton-rich nuclei. The generic equation is: See more If the proton and neutron are part of an atomic nucleus, the above described decay processes transmute one chemical element into another. For example: 55Cs → 56Ba + e + … See more
