Ionization,Excitation Energies and Fine Structure for 1s^2 nd( 3 ≤n ≤9) of Ion Cu^(26+)

利用全实加关联的理论方法计算了具有较高核电荷(Z=29)的Cu26+离子1s2nd(3≤n≤9)态的非相对论能量.在计算体系的总能量时,考虑了离子实和角动量分波对能量的修正、一阶相对论效应和质量极化效应对能量的修正、量子电动力学(QED)效应对能量的修正以及高阶相对论效应对能量的修正.给出了Cu26+离子1s2nd(3≤n≤9)态的电离能、激发能和精细结构劈裂.得到的计算结果与实验数据及物理规律符合的很好.

The non-relativistic energies of 1 S2 nd （ 3 3≤n ≤ 9 ） of ion Cu26 ＋ with higher nuclear charge （Z = 29 ） have been calculated by means of the full-core plus correlation （FCPC）. When the total energies of the system were calculated, we have considered the energy correc- tions of ion core and angular momentum, of first-order relativistic effect and mass polarization, of quantum electrodynamics and the higher-order relativistic effect. The ionization energy, exci- tation energy and fine structure splitting for l s2nd （3 3≤n ≤9） of ion Cu26＋ have been derived. The calculation outcome fits in with the experimental data and physical law.
