英文摘要: Based on the most advanced relativistic program GRASP92/2K to calculate atomic structures and properties as well as the corresponding codes to deal with electron collision dynamics processes, which have been developed recently by us, in this project we will develop some new theoretical methods and programs to study the polarization properties of radiative lines formed in the electron collision dynamics processes of highly charged ions, such as, electron impact excitation, dielectronic recombination, and radiative recombination. With the use of these new methods and programs, some further studies on influences of relativistic effect, Breit interaction, and electron correlation effect to polarization properties will be carried out, and detailed calculations on polarization properties of radiative lines interested in astrophysical plasmas, MCF, ICF, and ITER studies will be presented. We hope that these studies can provide important help for the related applications.
