Quasi-free Scattering Experiments with Radioactive Beams — •Felix Wamers for the R3B collaboration — Gesellschaft für Schwerionenforschung mbH, Darmstadt
An important part of the physics programme at the future R3B (Reactions with Relativistic Radioactive Beams) experiment at FAIR will be based on the study of a kinematically complete measurement of proton-induced reactions. These are in particular the quasi-free scattering processes of the type (p,2p), (p,pn), (p,pα) to study the single-particle and cluster structure of neutron-proton asymmetric nuclei, the role of nucleon-nucleon correlations in nuclei as a function of isospin, binding energy, and density, as well as the in-medium effects on the nucleon-nucleon interaction.
A prototype setup for detecting the high-energy protons in (p,2p) reactions in coincidence with forward emitted light particles and heavy fragments has been built based on an array of Si micro-strip detectors plus NaI detectors. First results from pilot experiments on quasi-free scattering in inverse kinematics using 17Ne and 12C beams at around 500 MeV/u will be presented.
