高电荷态离子光复合过程的研究不仅对于强库仑场中量子电动力学（QED）效应的精确研究、全相对论碰撞理论的检验、以及核与电子相互作用的高阶效应的研究具有重要的理论价值，而且对于等离子体状态的诊断、天体光谱的模拟和受控热核聚变的应用研究也具有十分重要的实际意义。本项目拟在先进的相对论多组态Dirac-Fock理论方法和相关程序的基础上，进一步发展研究辐射复合和双电子复合过程中各种辐射跃迁谱线极化特性、角微分截面、多极效应和干涉效应的方法和程序，并系统研究电子关联效应、相对论效应、QED效应及核效应对高电荷态离子结构、性质、极化特性及复合动力学过程的影响，以期有效的为相关实验研究提供理论支持。

The study of the photorecombination process for highly charged ions not only has important theoretical significance for the accurate measurement of the quantum electrodynamics (QED), the test of the relativistic collision theory and the research for higher-order effects of the interaction between electrons and nucleus, but also has application value for the plasma diagnostic, the theoretical modeling of the astronomical spectroscopy and the applied research of the controlled thermonuclear fusion reactions. Based on the multi-configuration Dirac-Fock theory and related software package, the method and program will be developed to calculate the polarization properties of radiative lines,the angular differential cross section, multipole effect and interference effect in the photorecombination presess. With the help of these new methods and progroms, we will be systematically studied that the electron correlation, relativistic and QED effect, and nucleus size effect influence on the structure and properties, polarization characteristics and recombination dynamics of highly charged ions. We hope our results will be helpful for the related experimental investigation.
