Abstract: Based on the improved isospin dependent quantum molecular dynamics (ImIQMD) model，the reaction of 48Ca+208Pb at energies near the Coulomb barrier was investigated systematically. The capture cross section，the quasifission cross section, the mass distribution of the quasifission fragments and the time for quasifission happened were obtained. According to the comparison with experimental data，the calculated capture cross sections and the fragment distributions of the quasifission were reasonable. Additionally，we got the cross sections of the third largest fragment，and the emission mechanism was also discussed briefly.
