Abstract

The β decay of ${}^{13}O$ has been studied at the IGISOL facility of the Jyväskylä accelerator centre (Finland). By developing a low-energy isotope-separated beam of ${}^{13}O$ and using a modern segmented charged-particle detector array an improved measurement of the delayed proton spectrum was possible. Protons with energy up to more than 12 MeV are measured and the corresponding $\log (ft)$ values extracted. A revised decay scheme is constructed. The connection to molecular states and the shell model is discussed.
