本文应用改进的量子分子动力学模型(ImQMD05版)分别接统计衰变模型(GEM2)和GEMINI模型研究了GSI近年采用反运动学方法测量的质子引起的散裂反应反应产物的质量分布。其中,ImQMD05计算中采用SkPSkyrme力,GEM2模型和GEMINI模型中各自仅有1个可微调参数。研究表明,在质子在重靶(208Pb,197Au,238U)上的散裂反应产物的质量分布用ImQMD In this paper, we use the modified Quantum Molecular Dynamics Model (ImQMD05) to measure the mass distribution of proton-induced spallation reaction products measured by inverse kinematics in recent years by the GEM2 and GEMINI models respectively. Among them, the use of SkPSkyrme force in ImQMD05 calculation, GEM2 model and GEMINI model only one can be fine-tuning parameters. Studies have shown that the mass distribution of the spallation reaction products on protons at the heavy targets (208Pb, 197Au, 238U) is determined with ImQMD
