Proton‐Rich Sulphur and Nucleosynthesis in Classical Novae

The structure of proton‐unbound states in S30 and S31 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, Jπ = 3+ and 2+ resonances in 30S. To search for evidence for these levels, the structure of S30 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.
