The main problem in the inertial confinement fusion is to achieve a high efficiency of implosion. We have a plasma with intermediate coupling in the course of implosion of fuel targets and it is essential to clarify various properties of such plasmas. Another important aspect of these targets is the fact that a considerable amount of heavy ions are included in their structure as a pusher or a tamper. When heavy ions are more or less separated from fuels, we have a system with interfaces between the strongly coupled part composed of these ions and the fuel plasma with weak or intermediate coupling. When they are mixed with fuels, we have a mixture of ions where ions with larger charge numbers mainly determine transport properties including radiation transfer. In this project, we have investigated, through theoretical analyses and numerical simulations, 1. properties of homogeneous plasmas with intermediate or strong coupling, especially those of ionic mixtures, 2. interfaces of strongly coupled plasmas, and 3. internal structure (electronic states) of heavy ions in plasmas.The largest problem left for the future may be to apply these results in realistic, large scale simulations of implosion and to optimize the target structure and the beam profile.

惯性限制融合的主要问题是实现高效率的内爆。在燃料目标的内爆过程中，我们有一个具有中间耦合的等离子体，至关重要的是要阐明这种等离子体的各种特性。这些目标的另一个重要方面是一个事实，即将大量的重离子作为推动者或篡改都包含在其结构中。当重离子与燃料分离或多或少分离时，我们将具有一个由这些离子组成的强耦合部分与具有弱或中间耦合的燃料等离子体之间的接口。当它们与燃料混合时，我们将具有离子的混合物，其中较大电荷数的离子主要决定传输特性，包括辐射转移。在这个项目中，我们通过理论分析和数值模拟研究了1。具有中间或强耦合的均质等离子体的性质，尤其是离子混合物的耦合，2。强烈耦合等离子体的接口和3。内部结构（电子状态）（电子状态）（电子状态）（电子状态）（电子状态）（电子状态）血浆中重离子中的重离子的最大问题可能是将这些结果应用于内爆的大规模模拟，并优化目标结构和梁曲线。
