Abstract
The energy at which collective transverse flow in the reaction plane d isappears, the balance energy E(bal), is found to depend on the isospi n of the system using the reactions Fe-58 + Fe-58 and Ni-58 + Ni-58. T he more neutron-rich system exhibits higher balance energies for all m easured impact parameters, in agreement with the predictions of a tran sport model which incorporates an isospin dependent mean field and iso spin dependent in-medium nucleon-nucleon cross sections.
