Beta-delayed proton emission from ${}^{21}$Mg

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 0.39MeV and 7.2MeV 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.
