Dipole polarizability of neutron rich tin isotopes — •Andrea Horvat1,2, Thomas Aumann1,2, Konstanze Boretzky2, Dominic Rossi1,2, Fabia Schindler1,2, Philipp Schrock3, and Dmytro Symochko1 for the R3B collaboration — 1TU Darmstadt, Germany — 2GSI Helmholtzzentrum, Darmstadt, Germany — 3CNS, University of Tokyo, Japan
Collective excitation modes in neutron rich nuclei contain valuable information about the isospin dependence of the nuclear equation of state (EOS). A key observable in this regard is the dipole polarizability, a quantity shown be strongly related to the EOS slope parameter L.
To this purpose an experimental campaign aimed at measuring the dipole response of the neutron rich side of the tin isotopic chain (124−132Sn) has been conducted at GSI Helmholtzzentrum für Schwerionenforschung. The method used was relativistic Coulomb scattering in inverse kinematics. The present status of the analysis will be presented.
