 Topic 9: The reaction 17 O(α,n)20 Ne and its impact on the s process in massive stars

             The ratio between the rates of the reactions 17O(α,n)20Ne and 17O(α,γ)21Ne determines whether O is an efficient neutron poison for the s
             process in massive stars, or if most of the neutrons captured by 16O(n, γ ) are recycled into the stellar environment. This ratio is of particular      
             relevance to constrain the s process yields of fast rotating massive stars at low metallicity.



            Guideline

            1. Motivation: stelar scenarios, role of the reaction in stellar nucleosynthesis, previous attemps to investigate this reaction.

             2. Description of the experiment: accelerator, experimental setup.

             3. Discussion of the results.
