摘要: Abstract Azimuthal distributions of charged particles and intermediate mass fragments emitted in Au+Au collisions at 600 A MeV have been measured using the FOPI facility GSI-Darmstadt. Data show a strong increase in-plane azimuthal anisotropy ratio with charge detected fragment. Intermediate are found to exhibit momentum-space alignment respect reaction plane. The experimental results presented as function polar centre-of-mass angle over broad range impact parameters. They compared predictions Isospin Quantum Molecular Dynamics model three different parametrisations equation state. We that such highly accurate data provide stringent test for microscopic transport models can potentially constrain separately stiffness nuclear state momentum dependence interaction.
