Co^(24+)离子1s^2nd(3≤n≤9)态的激发能和精细结构

Excitation energies and fine structure for 1s^2nd(3≤n≤9) states of Co^(24+)ion

用全实加关联方法计算了类锂Co24+离子1s2nd(3≤n≤9)态的非相对论能量;在考虑了一阶相对论效应和质量极化效应对体系能量的一级修正的基础上,估算了高阶相对论修正和QED修正对能量的影响,计算了该离子1s2nd态的电离能、激发能和精细结构,得到与现有实验数据符合得很好的结果.在此基础上,与量子亏损理论结合,实现了对Co24+离子任意高激发态(n≥10)的能量的可靠预言.

The non-relativistic energies of 1s2nd（3 ≤n≤9） states for Co24＋ion are calculated with the full-core plus correlation method.Based on the corrections of first-order relativistic contribution and mass-polarization effects,the higher-order relativistic contribution and QED correction to the energy are evaluated with hydrogenic approximation.The ionization potentials,excitation energies and fine structure for the 1s2nd states of this ion are calculated in this paper.The results agree satisfactorily with experimental data available in literature.Combining with quantum defect theory,the theoretical predictions on the energy of this ion are extrapolated to the higher excited states.
