英文摘要	By using the Improved Quantum Molecular Dynamics model, the Pu-244+Pu-244, U-238+ U-238 and Au-197+Au-197 reactions at the energy range of E-c.m. = 800 MeV to 2000 MeV are studied. We find that the production probability of superheavy fragments (SHFs) with Z >= 114 for the Pu-244+Pu-244 reaction is much higher compared with that for the U-238+U-238 reaction and no product of SHF is found for the Au-197+Au-197. The production probability of SHFs strongly depends on the incident energy and a narrowly peaked energy dependence of production probability is found. The decay mechanism of the composite system of projectile and target is studied and the time scale of decay process is explored. The binding energies and the shapes of SHFs are studied. The binding energies of SHFs are broadly distributed and the shapes of SHFs are strongly deformed.
