Isospin diffusion in binary collisions of S 32 + Ca 40,48 and S 32 + Ti 48 at 17.7 MeV/nucleon

The systems 32S + 40,48Ca and 32S + 48Ti at 17.7 MeV/nucleon were investigated with the setup general
array for fragment identification and for emitted light particles in dissipative collisions (GARFIELD) plus ring
counter (RCo) at Laboratori Nazionali di Legnaro (LNL) of Istituto Nazionale di Fisica Nucleare (INFN). Fusion
evaporation (FE), fusion fission (FF), and deep inelastic (DIC) events were identified, also through the comparison
with the prediction of a transport model (stochastic mean field, SMF), coupled to GEMINI++ as an afterburner.
This work mainly deals with the study of isospin transport phenomena in DIC events. In particular, the isospin
diffusion is highlighted by comparing the average isotopic content of the quasiprojectile (QP) remnants observed
when the target is the N = Z nucleus 40Ca and when it is the neutron-rich 48Ca. Also, the d/p and t/p ratios for
particles forward emitted with respect to the QP were found to increase with increasing N/Z of the target.
