γ-ray constraints on the properties of unbound 32Cl levels Academic Article uri icon

abstract

  • Systematic differences between measurements of excitation energies and branching ratios of unbound 32Cl levels near the proton threshold have recently emerged. We investigate these 32Cl properties using independent information by analyzing existing 32Ar(βγ)32Cl data and using published values from measurements of the 32S(3He,tγ)32Cl reaction. Significant evidence emerges in support of particular values. The results increase the thermonuclear rate of the 31S(p,γ)32Cl reaction by up to a factor of 2 over the temperature range of 0.4 to 2 GK that is reached during type I x-ray bursts on hydrogen-accreting neutron stars. © 2012 American Physical Society.
