Abstract
Mass measurements with a relative precision of better than 1.5x10{sup -8} were performed on Mg{sup 22} and its reaction partners Na{sup 21} and Na{sup 22} with the ISOLTRAP Penning trap mass spectrometer at CERN, yielding the mass excesses D(Mg{sup 22})=-399.92(27) keV, D(Na{sup 21})=-2184.71(21) keV, and D(Na{sup 22})=-5181.56(16) keV. The importance of these results is twofold. First, a comparative half-life (Ft value) has been obtained for the superallowed {beta} decay of Mg{sup 22} to further test the conserved-vector-current hypothesis. Second, the resonance energy for the Na{sup 21} proton capture reaction has been independently determined, allowing direct comparisons of observable {gamma} radiation in nova explosions with the yield expected from models.
