Abstract
The decays of the ground states of and have been studied in detail using the GREAT spectrometer. More than 7000 nuclei were produced in reactions of 290- and 300-MeV ions with an isotopically enriched target and separated in flight using the RITU separator. The proton and decays of the level were confirmed and the half-life and branching ratios of this state were determined with improved precision to be s and and , respectively. The -decay branch populated the ground state of , allowing improved values for the proton-decay energy and half-life to be obtained ( keV; ms). The decay of this level was identified for the first time and a branching ratio of was deduced. The spectroscopic factors deduced from these measurements are compared with predictions.
