Isospin transport in $^{84}Kr+^{112,124}Sn$ collisions at fermi energies with the FAZIA detector

Isotopically resolved fragments up to $Z\approx 20$ have been studied in a test experiment by the FAZIA Collaboration with a three-stage telescope. The reactions $^{84}Kr+^{112}Sn$ (n-poor) and $^{84}Kr+^{124}Sn$ (n-rich) at 35 MeV/nucleon were measured. The telescope was located near the grazing angle, so the detected fragments are mainly emitted from the phase-space region of the projectile. In the following, evidences for isospin diffusion and drift will be discussed.
