Beta-delayed proton emission from Mg-21
Beta-delayed proton emission from Mg-21 has been measured at ISOLDE, CERN, with a detection setup consisting of two charged-particle telescopes surrounding the decay point. Altogether 27 beta p branches were measured with center-of-mass energies between 0.4-7.2MeV. Seven new beta p branches were observed. Beta-delayed protons were used to determine the half-life of Mg-21 as 118.6 +/- 0.5 ms. From
