摘要：

Observation of β-delayed protons from the decay of the mass-separated Tz=-2 nuclide Mg20 (t12∼95 ms) establishes the mass excess of the lowest T=2 (0+) state in Na20 (13.42 ± 0.05 MeV), thereby completing the mass-20 isospin quintet. All members of this multiplet are bound to isospin-allowed particle-decay modes, providing the first test of the isobaric multiplet mass equation for such a quintet. Excellent agreement is observed using only the quadratic form of this equation. © 1978 The American Physical Society.
