This is a special spectrum, it was taken with PRA 5.0 using two sodium iodide detectors, in coincidence counting mode, to detect the annihilation gammas that are produced when 22Na undergoes beta+ decay. The positron instantly annihilates with an electron, producing two 511 keV gammas at a 180˚ angle. The two diametrically Na is the only stable (and the only primordial) isotope. It is considered a monoisotopic element and it has a standard atomic weight of 22.989 769 28(2). Sodium has two radioactive cosmogenic isotopes ( 22. Na, half-life = 2.605 years; and 24. Na, half-life ≈ 15 hours).

Calculate the energy released in the β + decay of 22 Na, the equation for which is given in the text. The masses of 22 Na and 22 Na are 21.994434 and 21.991383 u, respectively. (a) Write the complete β + decay equation for 11 C. (b) Calculate the energy released in the decay. The masses of 11 C and 11 B are 11.011433 and 11.009305 u
