The intensity of the 644-kev gamma -radiation is 0.22 plus or minus 0.04% relative to that or the 364 kev gamma radiation. It was also observed that the 507 kev gamma radiation occurs in coincidence with a BETA component, whose maximum energy iies between 246 and 332 kev. A new decay scheme is proposed. (auth)

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
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).

In and 22 58 Measurements of the electron capture to positron ratio in the decay of Na and Co are also described. Introduction 1. This paper is limited to those nuclear decay scheme parameters which are measured at NPL in conjunction with the programme* of standards of radioactivity viz - half lives, internal conversion coefficients, electron capture to positron ratios and y branching ratios.
