AB An investigation of the isospin equilibration process in the reactions 58;64Ni+58;64Ni at two bombardingenergies in the Fermi regime (32 MeV/nucleon and 52 MeV/nucleon) is presented. Datahave been acquired during the first experimental campaign of the coupled INDRA-FAZIA apparatusin GANIL. Selecting from peripheral to semi-central collisions, both the neutron content of thequasiprojectile residue and that of the light ejectiles coming from the quasiprojectile evaporationhave been used as probes of the dynamical process of isospin diffusion between projectile and targetfor the asymmetric systems. The isospin transport ratio technique has been employed. The relaxationof the initial isospin imbalance with increasing centrality has been clearly evidenced. Theisospin equilibration appears stronger for the reactions at 32 MeV/nucleon, as expected due to thelonger projectile-target interaction time than at 52 MeV/nucleon. Coherent indications of isospinequilibration come from the quasiprojectile residue characteristics and from particles ascribed tothe quasiprojectile decay.
