Abstract
Low-energy resonances in 31P(p,a)28Si and 35Cl(p,a)32S were studied directly in order to gain a
better understanding of reaction cycling in the Si-Ar region in novae, supernovae, and X-ray bursts.
Resonance strengths at Ec:m = 600 and 622 keV in 31P(p,a)28Si were measured as well as the Ec:m:
= 611 keV resonance in 35Cl(p,a)32S, the lowest energy that any resonance in this reaction has been
observed. The strengths of these resonances were found to be lower than previously determined
through indirect methods, resulting in weak cycling in the Si-Ar region.
