ABSTRACT The quasi-projectile (QP) properties are investigated in the Ar+Ni collisions at 95 AMeV taking into account the intermediate velocity emission. Indeed, in this reaction, between 52 and 95 AMeV bombarding energies, the number of particles emitted in the intermediate velocity region is related to the overlap volume between projectile and target. Mean transverse energies of these particles are found particularly high. In this context, the mass of the QP decreases linearly with the impact parameter from peripheral to central collisions whereas its excitation energy increases up to 8 AMeV. These results are compared to previous analyses assuming a pure binary scenario.
