Isospin Transport at Fermi Energies
In this paper we investigate isospin transport mechanisms in semi-peripheral
collisions at Fermi energies. The effects of the formation of a low density
region (neck) between the two reaction partners and of pre-equilibrium emission
on the dynamics of isospin equilibration are carefully analyzed. We clearly
identify two main contributions to the isospin transport: isospin diffusion due
to the ratio and isospin drift due to the density gradients. Both effects
are sensitive to the symmetry part of the nuclear Equation of State (EOS), in
particular to the value and slope around saturation density.Comment: 6 pages, 6 figures, revtex4-twocolumn
