Simulation of nucleon knockout reactions in a semiclassical eikonal approach — •Stefan Typel — TU Darmstadt, Fachbereich Physik, Institut für Kernphysik — GSI Helmholtzzentrum für Schwerionenforschung, Theorie

Nucleon knockout reactions are a valuable tool to study atomic nuclei, in particular their single-particle structure and neutron skin thickness. At beam energies of a few hundred MeV per nucleon, the reaction cross section can be calculated conveniently in the eikonal approach using the imaginary part of nucleus-nucleus or nucleus-nucleon optical potentials. These are obtained from recently improved parameterizations of nucleon-nucleon scattering cross sections including their angular distribution and Pauli-blocking effects. Cross sections of various processes, e.g., one- and two-nucleon removal or charge-changing reactions are calculated using nuclear structure input from a relativistic energy density functional. The reaction process is described in a Monte-Carlo simulation to take higher-order effects into account. Results for various reactions will be presented.
