摘　　要：利用约束的量子分子动力学(CoMD)模型研究了136Xe+198Pt反应系统在炮弹实验室系能量为7.98MeV/nucleon的多核子转移反应.通过检查原子核中核子在坐标空间中的分布情况,采用了与实验结合能、均方根半径较接近的原子核作为初始核.对比分析了实验与理论计算的电荷数从Z=50至58的同位素产生截面.结果表明:CoMD模型计算能够很好地再现实验测得的同位素产生截面.The multinucleon transfer reaction in 136Xe +198Pt reaction system was investigated with projectile nuclei energy of 7.98 MeV/nucleon in a laboratory system using a constraint quantum molecular(CoMD)model. By examining the distribution of their nucleons in coordinate space,the initial nuclei which were close to their experimental binding energies and root-mean-square radii were used. The cross sections of isotope productions with charge number from Z=50 to 58 calculated by experiment and theory are compared and analyzed. The results show that the Co MD model can reproduce the cross sections of isotope productions.
