Isospin Dependence of Collective Flow in Heavy-Ion Collisions at Intermediate Energies
B.A. Li, Z. Ren1, C. M. Ko, S.J. Yennello

Within the framework of an isospin-dependent Boltzmann-Uehling-Uhlenbeck model using initial proton and neutron densities calculated from the nonlinear relativistic mean-field theory, we compare the strength of transverse collective flow in reactions 48Ca+58Fe and 48Cr+58Ni, which have the same mass number but different neutron/proton ratios. The neutron-rich system (48Ca+58Fe) is found to show significantly stronger negative deflection and consequently has a higher balance energy, especially in peripheral collisions.
