Proton-rich sulphur and nucleosynthesis in classical novae
Abstract
The structure of proton-unbound states in 30S and 31S is important for determining the 29P(p, γ) 30S and 30P(p,γ) 31S reaction rates, which influence explosive hydrogen burning in classical novae. The former reaction rate in this temperature regime had been previously predicted to be dominated by two low-lying, unobserved, J π=3 + and 2 + resonances in 30S. To search for evidence for these levels, the structure of 30S was studied using the 32S(p,t) 30S reaction with a magnetic spectrograph. We provide an update on the status of the ongoing analysis and some preliminary results. © 2011 American Institute of Physics.
