The BUU formalism with an inclusion of fluctuations was used to study a mechanism of isospin equilibration in semi-peripheral collisions of heavy ions at energies close to the Fermi energy. A low density OneckO region which is created at the interface between interacting nuclei plays an important role in the transport of neutrons and protons between the projectile and the target. This isospin transport is affected by an interplay between drift and diffusion which are both sensitive to the density dependence of the asymmetry term in nuclear equation of state (EOS). The imbalance (isospin transport ratio) parameter was used as a measure of isospin equilibration. The comparison with experiment seems to favor a more asy-stiff nuclear equation of state.
