摘要
介绍了本课题组在基于多组态Dirac-Fock理论方法基础上发展的研究电子-离子(原子)碰撞激发过程的全相对论扭曲波方法,给出了利用这种方法对氦原子和类氦离子、锂原子、类铍离子、类氖离子、类镍离子以及氙原子的电子碰撞激发过程的最新研究成果.
Electron impact excitations plays a very important role in the modeling and diagnostics of astrophysical and laboratory plasmas, as well as in the development of X-ray laser schemes. Recently, a fully relativistic distorted wave method and the corresponding computational procedure REIE06 have been developed by us on the base of the multi-configuration Dirac-Fork （MCDF） method and the program packages GRASP92 and RATIP. In this paper, some latest research progresses on electron impact excitations of helium atom, helium-like ions, lithium atom, beryllium-like ions, neon-like ions, nickellike ions and xenon atom are presented.
