The (p,γ) Reaction Measurement Campaign at GSI: The Story of Capture Reaction Studies Using the Experimental Storage Ring

Highly-charged stable or radioactive ions can be stored and cooled in a heavy-ion storage ring offering unprecedented capabilities for precision studies for the atomic, nuclear structure, and astrophysics [1]. We have employed the unique feature of the Experimental Storage Ring (ESR) facility at GSI to address astrophysically relevant reactions. Starting from 2009, we carry out our proton-capture experimental campaign focusing on the measurement of (p,γ) reactions for hot, explosive scenarios. Using Double Sided Silicon Strip Detectors (DSSSD) in the ultra-high vacuum environment of the Experimental Storage Ring the 96Ru(p,γ)97Rh [2], 124Xe(p,γ)125Cs [3] and the recent 18Te(p,γ)119I experiments were successfully implemented until early this year, March 2020. In this seminar talk, the development of the measurement technique and of the sensitivity for the identification of p-capture products will be shown step by step given a highlight especially on the latest pioneer (p,γ) experiment using radioactive, highly charged ions.
