The end result of radioactive decay is the creation of a stable atomic nucleus. EMPIRICAL VALUES OF HIGHER-ORDER MATRIX ELEMENTS IN FIVE HINDERED-ALLOWED $beta$-DECAYS: $sup 22$Na, $sup 182$Ta, $sup 56$Mn, $sup 58$Co, $sup 32$P. 2010-02-18 In nuclear physics, beta decay (β-decay) is a type of radioactive decay in which a beta particle (fast energetic electron or positron) is emitted from an atomic nucleus, transforming the original nuclide to an isobar of that nuclide. For example, beta decay of a neutron transforms it into a proton by the emission of an electron accompanied by an antineutrino; or, conversely a proton is Enter the nuclear equation for the positron emission of 2211Na (sodium-22). Express your answer as a nuclear reaction.

The ratio of electron capture to positron emission in the decay of ${\\mathrm{Na}}^{22}$ to the 1.28-Mev level in ${\\mathrm{Ne}}^{22}$ has been determined by a comparison of the intensities of positron emission and 1.28-Mev radiation. The measurements were made with a coincidence arrangement employing a $4\\ensuremath{\\pi}$ beta counter to detect the positrons and a scintillation counter for
