Astrophysics with storage rings: ¹²⁴Xe beam at ESR — •Zuzana Slavkovská^1,2, Jan Glorius^1,2, Christoph Langer^1,2, René Reifarth^1,2, and Yuri Litvinov² for the E108B collaboration — ¹Goethe Universität Frankfurt — ²GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt

The astrophysically motivated reaction ¹²⁴Xe(p,γ) was investigated at the Experimentier-Speicherring (ESR) at the GSI in Darmstadt in June 2016.

For the first time it was possible to measure proton capture cross sections down to the Gamow window of the p-process using a storage ring. A ¹²⁴Xe beam reacted with a hydrogen gas jet target at five different energies between 5.5 AMeV and 8 AMeV. A newly designed double-sided silicon strip detector (DSSSD) placed directly into the ultrahigh vacuum of the ESR was used to detect the reaction products.

In this talk the experimental set-up and method as well as the challenges and results of the experiment will be presented.

This project is supported by HGS-HIRe, HIC for FAIR, BMBF (05P15RFFAA) and GSI-F&E.
