Abstract Using the momentum- and isospin-dependent Boltmann--Uehling--Uhlenbeck (BUU) model, we investigate the transverse flow and balance energy in two isotopic colliding systems 48Ca+58Fe and 48Cr+58Ni by adopting different symmetry potentials. By comparing the results between the two colliding systems, we find that the difference between the balance energies of two isotopic systems can be considered as a sensitive probe to the density dependence of symmetry energy.
