Abstract

The elliptic-flow ratio of neutrons with respect to protons in re- actions of neutron rich Heavy-Ion at intermediate energies has been recently proposed as an observable sensitive to the strength of the sym- metry term in the nuclear equation of state (EOS) at supra-saturation densities. The recent results obtained from the existing FOPI/LAND data for 197Au+197Au collisions at 400 MeV/nucleon in comparison with the UrQMD model allowed a first estimate of the symmetry term of the EOS but suffer from a considerable statistical uncertainty. In order to obtain an improved data set for Au+Au collisions and to ex- tend the study to other systems, a new experiment was carried out at the GSI laboratory by the ASY-EOS collaboration in May 2011.
