Proton-induced knockout reactions with light radioactive beams at R3B — •Leyla Atar — TUD, Schlossgartenstr.9, 64289 Darmstadt, Germany
Proton-induced knockout reactions are one of the main goal of the experimental program at the future R3B (Reactions with Relativistic Radioactive Bemas) Experiment at FAIR. It allows us to obtain spectroscopic information about valence and deeply bound single-nucleon states and to study their evolution over a large variation in isospin. Recent studies have shown that the occupancies of loosely bound valence nucleons in neutron- or proton-rich nuclei have a spectroscopic factor close to unity, whereas single-particle strength for deeply bound nucleons is suppressed in isospin asymmetric systems compared to the predictions of the many-body shell model. Further experimental and theoretical studies are needed for a qualitative and quantitative understanding.
For this aim a series of measurements have been performed on the complete oxygen isotopic chain using the existing experimental setup LAND/R3B at GSI. We will present the main scientific goals, the concepts of the experiment and the preliminary results.
