摘要
The squeeze-out flow in the reactions of Sn-124 + Sn-124 and Ba-124 + Ba-124 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 squeeze-out flow. This isospin dependence of the squeeze-out flow is shown to mainly result from the isospin dependence of nucleon-nucleon cross section and the symmetry energy. Meanwhile, it is indicated that the squeeze-out flow depends strongly on the impact parameter and incident energy.
