Microscopic Study of Dynamical Mechanism of Nucleus-Nucleus Reaction

中能重离子反应：（1）在量子分子动力学（QMD）中首次成功稳定了初始条件。计算了动态产生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、抛射体碎片自旋极化等，并与实验数据进行了拟合。(2)我们首次成功地构建了一个量子力学微观模拟理论，我们称之为反对称分子动力学（AMD）。壳效应是可描述的，并计算了动态α粒子产生的大截面。对团簇的质量和动量分布的计算表明，与实验数据吻合得很好。(3)用绝热冷却方法构造原子核基态是一种新颖而成功的研究原子核结构的方法。重排反应：在6-8核子体系中，我们进行了多道耦合微观计算，成功地再现了反应总截面。我们得到的最重要的认识是，单核子转移通道总是必不可少的，并且氘核的赝态是重要的。

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.
