Abstract
A multihit capacity setup was used to study the decay of the dripline nucleus , produced at the ISOLDE facility at CERN. A spectroscopic analysis of the -delayed three-proton decay of is presented for the first time together with a quantitative analysis of the -delayed 2 decay. A new method for determination of the spin of low-lying levels in the daughter using proton-proton angular correlations is presented and used to determine that the spin of the 5.2-MeV level is most likely with also possible. The half-life of is found to be 15.1(3) ms. An improved analysis of the Fermi strength including the 3-decay mode gives a total measured branching ratio of , which is lower than the theoretical value found to be . Finally, a previously unidentified transition from the isobaric analog state in the decay of has been found.
