Abstract
A value of s has been deduced for the half-life of the ground state of , in sharp contrast to the previously adopted value of s. Access to the low-spin ground state was accomplished via β decay of the parent nuclide. New low-energy states in have been identified from β-delayed γ-ray spectroscopy. The new, shorter half-life of is not suggestive of isospin-forbidden β decay, and new spin and parity assignments of and have been adopted for the ground and isomeric β-decaying states, respectively, of .
