Abstract
Mass measurements with a relative precision of better than were performed on and its reaction partners and with the ISOLTRAP Penning trap mass spectrometer at CERN, yielding the mass excesses , , and . The importance of these results is twofold. First, a comparative half-life ( value) has been obtained for the superallowed decay of to further test the conserved-vector-current hypothesis. Second, the resonance energy for the proton capture reaction has been independently determined, allowing direct comparisons of observable radiation in nova explosions with the yield expected from models.
