Abstract
Charged-particle decay spectroscopy of heavy suburanium isotopes produced by projectile fragmentation of 1Â GeV/u 238U was tested using a simple implantation-decay set-up equipped with fast-reset preamplifiers. The products were separated and identified with the GSI fragment separator (FRS) and implanted into a stack of Si detectors. Measurements were performed of implantation decay correlations of nuclei with half-lives in the range of 0.1-100Â ms. Yields of very neutron-deficient protactinium, thorium and actinium isotopes were measured and yield extrapolations imply that with the availability of a beam intensity of 109Â ions/s, projectile fragmentation of relativistic 238U can be an effective method to access new nuclear species including possible proton emitters in the suburanium region.
