Quasi-free scattering experiments in inverse kinematics — •Valerii Panin — GSI, Planckstrasse 1, 64291 Darmstadt, Germany
An important part of the physics program at the future R3B (Reactions with Relativistic Radioactive Beams) experiment at FAIR will be based on the study of kinematically complete measurements of proton-induced reactions. These are in particular the quasi-free scattering processes of the type (p,2p), (p,pn), (p,pα) etc, which will be used 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. A prototype setup for the detection of 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 for tracking and thick NaI scintilators for energy measurements. A 12C beam has been chosen for the bench-mark experiment since its structure is well known, and results from proton- as well as electron-induced knockout reactions are available. First results from this experiment performed in inverse kinematics at the LAND-R3B setup will be discussed in this presentation.
