Beta-delayed proton emission from
Mg has been measured at ISOLDE, CERN, with the ISOLDE Decay Station setup including both charged-particle and
-ray detection capabilities. A total of 27 delayed proton branches were measured including seven so far unobserved. An updated decay scheme, including three new resonances above the proton separation energy in
Na and more precise resonance energies, is presented. Beta-decay feeding to two resonances above the Isobaric Analogue State in
Na is observed. This may allow studies of the 4032.9(2.4) keV resonance in
Ne through the beta decay of
Mg, which is important for the astrophysically relevant reaction

Ne. Beta-delayed protons were used to obtain a more precise value for the half-life of
Mg, 91.4(1.0) ms.
