The Stability and Radioactivity of Atomic Nucleus

A Deuterium’s nucleus consists of a proton and a neutron, which two protons and a π-meson, is stable; the nucleus of Helium-3 consists of two protons and a neutron, which three protons and a π-meson, is stable. [1] A Tritium’s nucleus consists of a proton and two neutrons, which three protons and two π-mesons, it is unstable. But, since a Tritium’s nucleus has only a proton, there is no exist the Coulomb repulsion between of protons inside a Tritium’s nucleus, so we get the Coulomb repulsion between of protons is not the reality causes for atomic nucleus in unstable state and has radioactivity. The reality causes for atomic nucleus in unstable state and has radioactivity is: Compared with a stable Helium-3, a Tritium’s nucleus has a redundancy π-meson and excess energy, until freed the redundancy π-meson [π=e-(β)+Ne(γ)] and excess energy, after attenuation become Helium-3, reaches in stable state. In short, atomic nucleus ’ energy is produced by neutrons and their π-mesons, the energy levels of atomic nucleus is determined by N/A, or (AZ)/A, one kind of nuclide has radioactivity, is because it contains redundancy neutrons, or mor
