Proton‐Rich Sulphur and Nucleosynthesis in Classical Novae

摘要

The structure of proton‐unbound states in ~(30)S and ~(31)S is important for determining the ~(29)P(p,γ)~(30)S and ~(30)P(p,γ)~(31)S 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 ~(30)S. To search for evidence for these levels, the structure of ~(30)S was studied using the ~(32)S(p,t)~(30)S reaction with a magnetic spectrograph. We provide an update on the status of the ongoing analysis and some preliminary results.
