Indirect measurements of neutron-induced reaction cross sections at storage rings

Neutron-induced reaction cross sections of unstable nuclei are essential for understanding the synthesis heavy elements in stars. However, their measurement is very difficult due to radioactivity targets involved. We propose circumvent this problem by using first time surrogate method inverse kinematics at heavy-ion storage rings. In contribution, we describe developments have done perform surrogate-reaction studies rings GSI/FAIR. particular, present results proof principle experiment, which conducted recently Experimental Storage Ring (ESR).
