Abstract：
Within the framework of an isospin-dependent quantum molecular dynamics model, the balance energy has been calculated for reaction systems ⁵⁸Fe+⁵⁸Fe and ⁵⁸Ni+⁵⁸Ni at different impact parameters. It is shown that the balance energy of the neutron-rich system ⁵⁸Fe+⁵⁸Fe is higher than that of the system ⁵⁸Ni+⁵⁸Ni, which could be in qualitative agreement with the results of the experiments.
