Using (p,n) reactions to probe various neutron-induced nucleosynthesis scenarios.

Neutron-induced reactions are key to understand a variety of nucleosynthesis problems. More often than not, however, it is rather hard or even impossible to obtain experimental data on the nuclear reactions of interest that typically involve the reaction of a radioactive nucleus with neutrons. Such reactions are very difficult to measure for short-lived nuclei as neither of the reacting parts can be made into a target. An important effort is being undertaken by the nuclear astrophysics community to find ways to mitigate this experimental limitation using both theory and experiment. While the effort is mostly focused on neutron capture reactions, various astrophysics problems rely critically on the knowledge of reaction rates for (n,p) reactions. In this talk, I will focus on (n,p) reaction rates, and I will present experimental results of our technique that uses (p,n) reactions to constrain (n,p) reactions for nucleosynthesis.
