摘要By using the improved Quantum Molecular Dynamics model, the Pu-244+(PU)-P-244, U-238+U-238 and (197)An+ 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(SHF) with Z >= 114 is much higher for Pu-244+Pu-244 reaction compared with that of U-238+U-238 reaction and no product of SHF is found for the Au-197+Au-197. The production probability of SHF is narrowly peaked in the dependence of incident energies. The decay mechanism of the composite system of projectile and target and the time scale of decay process are explored. The binding energies of superheavy fragments are found to be broadly distributed and their shapes turn out to be exotic form.
