摘　　要：利用全相对论组态相互作用(RCI)方法和多组态Dirac-Fock(MCDF)方法,采用GraspVU程序,系统地研究了镁的高离化态He-like到Ne-like的KαX射线的性质,其内容主要包括电偶极跃迁能级、跃迁几率、振子强度和线强度,以及Breit修正、量子电动力学QED效应和核的有效体积效应对能级的影响.计算结果与其他已有的理论和实验值吻合得很好,说明该计算方法是可靠的.In this paper,by using relativistic configuration interaction （RCI） and multi-configuration Dirac-Fock （MCDF） methods in the active space interaction approach,the Kα X-ray transitions including transition energies, probability, oscillator strengths and line strengths for the states of He-like through Ne-like are studied in the extended optimal level scheme. Additionally, the contributions from Breit interaction,quantum electrodynamics （QED） and nuclear mass corrections to the initial and final levels have been taken into account. Our calculated values are compared with other available data are found to be in good agreement with them. This could justify our present calculated results to be reliable.
