Abstract：
The entrance-channel effects and dynamical mechanisms on the fusion reaction of ⁷⁴Ge+⁷⁴Ge and ⁴⁸Ti+¹⁰⁰Mo are studied with the microscopic transport model-Improved Quantum Molecular Model(ImQMD). The time evolution of the〈r²〉^1/2 and β of the compound nuclei are analyzed, and these results show that the lager deformation of the compound nuclei are more easily produced for the mass symmetry reaction system ⁷⁴Ge+⁷⁴Ge than that for the mass asymmetry reaction system ⁴⁸Ti+¹⁰⁰Mo. The final results on the larger deformed compound nuclei are determined by this dynamical process.
