Two new excited states in Na ²³ (2.405 MeV and 2.87 MeV) have been found. The spin of the 2.705 MeV state was found to be {7}/{2}.

The positron instantly annihilates with an electron, producing two 511 keV gammas at a 180˚ angle. The two diametrically ejected gamma rays are detected using two NaI detectors and two GS-1100A and PRA 5.0. 22Na is the positron emitting nuclide and has a simple decay scheme with relatively long half life of 2.6 years, so that it is widely used in many applications. The decay scheme is shown in Figure l.1) Both positron and electron capture process decay to an exited state of 1.275 MeV, except for a very weak positron branch which goes directly Sodium-22 | Na | CID 6328543 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards 22 11 Na → 22 10 Ne + 0 + 1 e + + ν; 207 83 Bi + 0-1 e-→ 207 82 Pb + ν; 238 92 U → 234 90 Th + 4 2 He; Given the masses of relevant atoms and the mass change criteria for beta decay, we calculate: Δm = m[24 12 Mg] - m[24 11 Na] Δm = 23.9850419 u - 23.990963 u = -0.0059211 u ΔE = (-0.0059211 u)(931.494 MeV / u) = -5.515 MeV Na-22 Decay scheme Sodium 11 /10% 3.7 ps 90% Neon 22Na 22Ne + γ + β+ + υe.
