Ninety percent of the time, the nuclear decay proceeds by + emission, and these always annihilate with an electron to produce two 0.511 MeV gammas. Thus the rate of emission of 0.511 MeV gammas is 0:92 n= 1:8 Sodium-22 is a radioactive isotope of sodium, undergoing positron emission to 22 Ne with a half-life of 2.605 years. 22 Na is being investigated as an efficient generator of "cold positrons " (antimatter) to produce muons for catalyzing fusion of deuterium. It is also commonly used as a positron source in positron annihilation spectroscopy.

β+ decay is energetically possible only if the mass of the parent atom exceeds the mass of the daughter atom by at least two electron masses (2 x 0.000549 AMU or its energy equivalent, 1.02 MeV).

DISCUSSION OF THE DECAY SCHEME The results considered in the preceding sections make it possible to propose the decay scheme of Ne23 shown in fig. 5.
