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锌离子的波长、电偶极跃迁速率以及振子强度。利用活动空间扩大法，计算出的类氦和类铍的数据与实验数据符合很好。在此基础上本文给出了准确的锌离子类氦到类氖的跃迁特性。这些数据可以给锌等离子体的能级寿命、布居分布以及平均电荷提供参考。
Relativistic configuration interaction calculations with the inclusion of Breit interaction, quantum electrodynamics and finite nuclear mass corrections have been carried out in the extended optimal level scheme using multi- configuration Dirac-Fock wavefunctions on the wavelengths, electric dipole transition rates and oscillator strengths of Zinc. Through the use of the active space method, the calculated values are compared with the other available data on He-like and Be-like zinc and are found to be in very good agreement with them. In this paper, we give accurate transition properties from Zn XXI through Zn XXIX. These data provide reference value for level lifetime, charge state distribution and average charge of zinc plasmas.
