Direct Reaction Experiments in Inverse Kinematics: Storage Rings vs. Active Targets

Since the pioneering experiments of Rutherford using light-ion scattering, this type of experiments became a major tool for extracting important information of the structure and bulk properties of nuclei. For example, elastic scattering at low momentum transfer provides insight into the nuclear matter radius. Inelastic scattering experiments at small angles enable the investigation of nuclear deformation and collective excitation modes. Transfer and charge-exchange reactions offer critical constraints for comprehending nuclear physics processes in stellar environments. However, experiments involving unstable nuclei require measurements in inverse kinematics, which can considerably influence the reaction luminosities. In order to overcome such limitations, novel techniques with efficient detection systems, such as storage rings and active targets, have been successfully used in recent years. Both techniques enable measurements at high luminosities and very low detection thresholds, which are ideal for inverse kinematics experiments. In this talk, I am going to show experimental results and discuss the capabilities and limitations of these techniques.
