  The neutron-proton equilibration process in 48 Ca+ 40 Ca at 35 MeV/nucleon
bombarding energy has been experimentally estimated by means of the isospin
transport ratio. Experimental data have been collected with a subset of the
FAZIA telescope array, which permitted to determine Z and N of detected
fragments. For the first time, the QP evaporative channel has been compared
with the QP break-up one in a homogeneous and consistent way, pointing out to a
comparable n-p equilibration which suggests close interaction time between
projectile and target independently of the exit channel. Moreover, in the QP
evaporative channel n-p equilibration has been compared with the prediction of
the Antisymmetrized Molecular Dynamics (AMD) model coupled to the GEMINI
statistical model as an afterburner, showing a larger probability of proton and
neutron transfers in the simulation with respect to the experimental data.
