摘要:
采用结合包含Breit相互作用、量子动力学效应和有限核质量修正的相对论的组态相互作用的方法以及多组态Dirac-Fock方法的能级优化法来计算类镁离子的波长、电偶极跃迁速率以及振子强度。利用活动空间扩大法,计算出的类镁数据与实验符合很好。在此基础上本文给出了4个类镁离子跃迁特性。这些数据可以给类镁等离子体的能级寿命、布居分布以及平均电荷提供参考。
Abstract:
Relativistic configuration interaction methods including Breit interaction, quantum electrody- namics and finite nuclear mass corrections have been carried out with the combination of the energy level optimization method of multi-configuration Dirac-Fock to calculate the wavelengths, electric dipole transition rates and oscillator strengths of Mg-like ions. Through the use of the ac- tive space expanding method, the calculated experimental data are compared with the other available data on Mg-like ions and are found in good agreement with them. In this paper we give accurate transition properties of four Mg-like ions. These data provide reference for level lifetime, charge state distribution and average charge of Mg-like plasmas.
