The positron instantly annihilates with an electron, producing two 511 keV gammas at a 180˚ angle. 4) Sodium-22 (Na-22) is radioactive and decays by beta plus decay mode. The half-life is 2.603 years. (a) Calculate the binding energy per nucleon for sodium-22. (b) Write the reaction for the decay. Na−22 Peak 1: Electron−Positron Annihilation at 511 keV Peak 2: Nuclear Energy Transition at 1.27 MeV 340 ± 30 keV 1068 ± 45 keV Compton Edge for Peak 1 Notice that the electron capture of Na-22 results in nuclear transmutation; the inner-orbital electron is captured by the nucleus, the result being the formation of a neutron from the combination of said electron with a proton from the nucleus.
