Decay of a Tz=-2 Nucleus: Argon-32 Academic Article uri icon


  • -delayed protons have been observed from Ar32 (t1275 msec), the most neutron-deficient nucleus whose radioactive decay has ever been recorded. From the proton spectrum, the T=2 state in Cl32 has been identified to have a mass excess of -8295.65.2 keV. As the fourth accurately known member of an isobaric quintet, it provides an accurate test for a cubic term in the isobaric-multiplet mass equation as applied to narrow T=2 states: The coefficient of such a possible term is determined to be 0.52.5 keV. 1977 The American Physical Society.
