Isotopic effects are studied in reactions induced by Ca40 projectiles at 25 MeV/nucleon on Ca40, Ca48, and Ti46 targets. The N/Z contents of projectilelike and midvelocity (MV) sources are probed by means of isotopic (Li7/Li6 and Be9/Be7) and isobaric (Li7/Be7) yield ratios, for semiperipheral events. In particular, information about isospin transport phenomena will be discussed. Isospin diffusion processes involving nuclei, which have noticeable differences in N/Z have been investigated. Signals of isospin drift, which are related to the gradient of density in the participant region, have also been observed for fragments emitted at MV.
