Abstract

Beta-delayed proton emission from $^{21}$ Mg has been measured at ISOLDE, CERN, with a detection setup including particle identification capabilities. $\beta$ -delayed protons with center of mass energies between 0.39 $\,$ MeV and 7.2 $\,$ MeV were measured and used to determine the half life of $^{21}$ Mg as $118.6\pm 0.5\,$ ms. From a line shape fit of the $\beta p$ branches we extract spectroscopic information about the resonances of $^{21}$ Na. Finally an improved interpretation of the decay scheme in accordance with the results obtained in reaction studies is presented.
