Abstract：
The projectile-like products at 5.3° in the reaction 35MeV/u 36Ar+ 124Sn were inclusively measured with good isotropic identification. With increasing kinetic energy, the average N/Z ratio of the products gradually decreases,approaching to that of the projectile. It is shown from the isospin dependent quantum mechanics(IQMD) that with the increasing of reaction time, the average kinetic energy of the projectile-like products decreases, while the N/Z ratio increases gradually. Moreover, the isotropic composition is obviously dependent on the impact parameter, and the N/Z ratio is becoming smaller with increasing collision centrality.
