Abstract
We perform a systematic study of in-plane and out-of-plane proton and neutron how from nucleus-nucleus collisions within the Boltzmann-Uehling-Uhlenbeck transport approach, employing different parameter sets for the mean-field potentials that can be characterized by the nuclear incompressibility and the stiffness of the momentum-dependent potential. We find that a simultaneous description of the experimental data from the BEVALAC and the SIS on both the nucleon squeeze-out nu (2) and the in-plane flow F at beam energies E-lab = 0.15-2 A GeV requires a mean field with strong momentum dependence, i.e., an effective Landau mass m* = 0.68m(0) at normal nuclear matter density rho (0)=0.17 fm(-3), where m(0)=0.938 GeV is the bare nucleon mass. Some experimental data on the squeeze-out require an even stiffer momentum dependence (m* approximate to 0.62m(0)). All systems investigated are found to be compatible with m*/m(0) = 0.65 +/- 0.03.
