Abstract
The squeeze-out flow in the reactions of Sn-124 + Sn-124 and Ba-124 + Ba-12 4 at different energies for different impact parameters was investigated by means of isospin-dependent quantum molecular dynamics model. It was found that the more neutron-rich system ( Sn-124 + Sn-124) exhibited weaker squee ze-out flow. This isospin dependence of the squeeze-out flow is shown to ma inly result from the isospin dependence of nucleon-nucleon cross section an d the symmetry energy. Meanwhile, it is indicated that the squeeze-out flow depends strongly on the impact parameter and incident energy.
