Direct reactions with light neutron-rich nuclei — •Leyla Atar — TU Darmstadt

Quasifree (p,2p) and (p,pn) knockout reactions with radioactive beams in inverse kinematics allow 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 current status of the analysis.
