摘要: A proton-proton coincidence experiment has shown that, following the superallowed beta decay of odd-odd, ${T}_{z}=\ensuremath{-}2$ nuclide, $^{22}\mathrm{Al}$, two protons are emitted with a summed energy spectrum (5.636, 4.139 MeV) characteristic to ground and first excited states $^{20}\mathrm{Ne}$, respectively.
