本文用改进的反对称化分子动力学模型研究了135 MeV/核子12 C +Fe反应碎片的质量产额分布。结果表明，理论计算与实验数据吻合较好，特别是轻碎片的质量产额。根据Vlasov方程预测的核子波包扩散的随机分裂对碎裂过程的描述产生了很大的影响。
An improved antisymmetrized molecular dynamics model has been applied to the study of the mass yield distribution for fragments of the12C+Fe reaction at 135 MeV/nucleon. It is shown that the experimental data are well reproduced by the theoretical calculation, especially for the mass yield of light fragments. The stochastic splitting of the nucleon wave packet according to its diffusion predicted by Vlasov equation has drastic effect on the description of fragmentation process.
