dc.abstract.enIsospin transport phenomena in dissipative heavy ion collisions have been investigated at Fermi energies with a beam of $^{8}Kr$ at 35AMeV. A comparison of the $\left \langle N \right \rangle /Z$ of light and medium products forward-emitted in the centre of mass frame when the beam impinges on two different targets, the n-poor $^{112}Sn$ and the n-rich $^{124}Sn$, is presented. Data were collected by means of a three-layer telescope with very good performances in terms of mass identification (full isotopic resolution up to Z $\sim$ 20 for ions punching through the first detector layer) built by the FAZIA Collaboration and located just beyond the grazing angle for both reactions. The $\left \langle N \right \rangle /Z$ of the products detected when the n-rich target is used is always higher than that associated to the n-poor one; since the detector was able to measure only fragments coming from the QuasiProjectile decay and/or neck emission, the observed behaviour can be ascribed to the isospin diffusion process, driven by the isospin gradient between QuasiProjectile and QuasiTarget. Moreover, for light fragments the $\left \langle N \right \rangle /Z$ as a function of the lab velocity of the fragment is observed to increase when we move from the QuasiProjectile velocity to the centre of mass (neck zone). This effect can be interpreted as an evidence of isospin drift driven by the density gradient between the QuasiProjectile zone (at normal density) and the more diluted neck zone.pl
