Professor Y. Kim and his coworkers have been at the forefront of research on the few-nucleon problem for twenty years. They have played a major role in the calculation of the properties of few-nucleon systems beginning with well-defined Hamiltonians. Professor Kim proposes a large and varied research program centered around three-nucleon physics, both bound-state and scattering calculations. The trinucleon continuum-state calculations are of great interest and importance, both to other theorists and to experimentalists, regarding the data to be obtained from proposed experiments. Research concerning photodisintegration and radiative capture, meson-exchange currents and three-nucleon forces, quark degrees of freedom in nuclei and relativistic light and heavy-ion collisions is also planned. Professor Y. Kim has been a leader in the analysis of the three-nucleon problem and has recently moved to quark-cluster models of light nuclei. He now proposes an extensive research program which would refine his previous work on the structure of the three-nucleon bound state using a baryons only model. Most importantly he plans to perform calculations of the trinucleon continuum states. The results of such calculations are needed for comparison with proposed experiments at the major nuclear physics accelerator centers. He also proposes theoretical investigations of the effects of quark degrees of freedom associated with few-nucleon systems and light nuclei. Numerous important and useful results will come from this research.

金教授和他的同事们20年来一直站在研究少核子问题的前沿。它们在计算从定义良好的哈密顿量开始的少核子系统的性质方面起了重要作用。金教授提出了一个以三核子物理为中心的大型和多样化的研究计划，包括束缚态和散射计算。三核子连续态计算对于其他理论家和实验家来说都是非常有趣和重要的，因为它涉及到从所提出的实验中获得的数据。此外，还计划进行光分解和辐射俘获、介子交换电流和三核子力、原子核中的夸克自由度和相对论性轻离子和重离子碰撞等方面的研究。金教授一直是分析三核子问题的领军人物，最近开始研究轻核的夸克簇模型。他现在提出了一个广泛的研究计划，该计划将改进他以前使用仅重子模型研究三核子束缚态结构的工作。最重要的是，他计划对三核连续态进行计算。这样的计算结果需要与主要核物理加速器中心提出的实验进行比较。他还提出了与少核子系统和轻核相关的夸克自由度效应的理论研究。这项研究将产生许多重要而有用的结果。
