摘要：

The energy at which collective transverse flow in the reaction plane disappears, the balance energy E(bal), is found to depend on the isospin of the system using the reactions Fe-58 + Fe-58 and Ni-58 + Ni-58. The more neutron-rich system exhibits higher balance energies for all measured impact parameters, in agreement with the predictions of a transport model which incorporates an isospin dependent mean field and isospin dependent in-medium nucleon-nucleon cross sections.
