Microscopic Study of Dynamical Mechanism of Nucleus-Nucleus Reaction

中能重离子反应：(1)首次在量子分子动力学(QMD)中实现了初始条件的稳定化。计算了动态产生的碎片的多步统计衰变。计算了聚变反应、Wilczynski图、碎片能谱、团簇质量分布、弹丸碎片的自旋极化等数据，并与实验数据进行了比较。(2)首次成功构建了反对称化分子动力学(AMD)的量子力学微观模拟理论。壳层效应是可描述的，并计算了大截面的动态α粒子产生。星系团质量和动量分布的计算结果与实验数据吻合较好。(3)摩擦冷却方法构建核基态被证明是研究核结构的一种非常新颖和成功的技术。重排反应：在6-8核子系统中，我们进行了多通道耦合微观计算，并成功地再现了反应总截面。我们得到的最重要的知识是，一核子的传输通道总是不可或缺的，而重离子的赝态是重要的。

Intermediate Energy Heavy Ion Reaction: (1) We succeeded the stabilization of the initial condition for the first time in quantum molecular dynamics (QMD). Multistep statistical decays of dynamically produced fragments were calculated. Fusion reaction, Wilczynski plot, energy spectra of fragments, cluster mass distribution, spin polarization of projectile fragments, and others were calculated and shown to fit the data. (2) We have succeeded for the first time to construct a quantum mechanical microscopic simulation theory, which we call antisymmetrized molecular dynamics (AMD). Shell effects are describable and large cross section of dynamical alpha-particle production was calculated. Calculations of mass and momentum distribution of clusters were shown to fit the data very well. (3) Frictional cooling method to construct nuclear ground states proved to be a very novel and successful technique for the study of nuclear structure. Magnetic moments of neutron-rich nuclei were very nicely and systematically reproduced.Rearrangement Reaction: In 6-8 nucleon systems we made multi-channel-coupling microscopic calculations and succeeded to reproduce total reaction cross sections. Most important knowledge we got is that one-nucleon transter channel is always indispensable and pseudo-states of deuteron are important.
