Abstract

Beta-delayed proton emission from Mg-20 has been measured at ISOLDE, CERN, with the ISOLDE Decay Station (IDS) setup including both charged-particle and gamma-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-20 and more precise resonance energies, is presented. Beta-decay feeding to two resonances above the Isobaric Analogue State (IAS) in Na-20 is observed. This may allow studies of the 4032.9(2.4) keV resonance in Ne-19 through the beta decay of Mg-20, which is important for the astrophysically relevant reaction O-15(alpha,gamma)Ne-19. Beta-delayed protons were used to obtain a more precise value for the half-life of Mg-20, 91.4(1.0)ms.
