Abstract An inclusive measurement was performed for 30 MeV/u 40Ar+58,64Ni and 115In. By employing the degree of freedom of N/Z, the production mechanism of the high energy component of the intermediate mass fragments (IMFs: 3 ≤ Z ≤ 13) has been discussed. Special attention has been paid to the target dependence of N/Z ratio of the energetic fragments. These IMFs may be produced by a projectile fragmentation process with energy dissipation.
