1. In Current Science, the alpha particle is the nucleus of the isotope Helium-4 consisting of two protons and two neutrons (4 nucleons). The alpha particle, along with the beta particle (electron), and the gamma ray (nuclear photon) , are the primary products of radioactive decay.
2. In Neu Theory, the alpha particle is the nucleus of the isotope Helium-4 , a two neucleon cluster consisting of two deuteron cells below two concentrically layered positive electric charge shells.« Back to Glossary Index
