Tritium is an isotope of hydrogen whose nucleus Triton contains 2 neutrons and 1 proton. Free neutrons decay into p + bare + barν. If one of the neutrons in Triton decays, it would transform into He3 nucleus. This does not happen. This is because triton energy is less than that of a He3 nucleus. Explanation: Isotopes: The atoms of elements having the same atomic number but different mass numbers are called isotopes. All isotopes have the same chemical properties. The isotopes of some elements are the following: 1H1, 1H2, 1H3 8I16, 8I17, 8I16 2He3, 2He4 17CI35, 17Cl37 92U235, 92U238 The nucleus of Tritium (1H3) contains 1 proton and 2 neutrons. In a neutron that decays as n -> p + bare + barv, the nucleus may have 2 protons and one neutron, i.e., tritium will transform into 2He3 (2 protons and 1 neutron). Triton energy is less than that of the 2He3 nucleus, i.e., transformation is not allowed energetically.
