Using the large acceptance apparatus FOPI, we study central and semi-central collisions in the reactions (energies in A GeV are given in parentheses): (40)Ca + (40)Ca (0.4, 0.6, 0.8, 1.0, 1.5, 1.93), (58)Ni + (58)Ni (0.15, 0.25, 0.4), (96)Ru + (96)Ru (0.4. 1.0, 1.5), (96)Zr + (96)Zr (0.4, 1.0. 1.5), (129)Xe + CsI (0.15, 0.25, 0.4). (197)Au + (197)Au (0.09, 0.12, 0.15, 0.25, 0.4, 0.6, 0.8, 1.0, 1.2, 1.5). The observables include directed and elliptic flow. The data are compared to earlier data where possible and to transport model simulations. A stiff nuclear equation of state is found to be incompatible with the data. Evidence for extra-repulsion of neutrons in compressed asymmetric matter is found. |
